  1. Instructor introduces the systematic diagnostic approach: verify complaint, gather history, test (compression, spark, fuel delivery), analyze results, identify root cause, recommend repair; students copy a diagnostic flowchart into their lab log.
  2. Fault-finding rotation: instructor pre-seeds five engines with one fault each (examples: broken flywheel key, stuck exhaust valve, scored cylinder, cracked reed valve, wrong oil level causing smoke); students rotate through each engine in 20-minute intervals, following the flowchart, and document findings on a work order without being told the seeded fault.
  3. Debrief and correction: after rotation, instructor reveals each fault; students compare their diagnosis to the actual fault, self-score their work orders, and discuss any missed steps as a group to reinforce systematic thinking.
Five pre-faulted engines (mix of two-stroke and four-stroke), compression tester, spark tester, multimeter set to ohms for coil check, OEM service manuals, diagnostic flowchart handout, service work order forms, lab log notebooksEach student's five work orders are graded: correct root cause identification = 2 pts, correct supporting evidence documented = 2 pts, appropriate repair recommendation = 1 pt, per engine; maximum 25 pts. Pass = 20 of 25 (80%). Any student who misdiagnoses a no-start safety-related fault (e.g., flywheel key) receives immediate instructor review.
7Engine Reassembly, Final Inspection, and Start-Up8labStudents will reassemble a complete four-stroke small engine from a short-block, perform a final inspection checklist, start the engine, and verify normal oil pressure indication and idle operation.
  1. Torque sequence drill: before assembly, students lay out all fasteners and verbally walk the instructor through the head-bolt torque sequence and value from the OEM manual; instructor initials the student's checklist before assembly begins.
  2. Full assembly: students install valve train components (where applicable), head, carburetor, air filter, blower housing, and ignition coil; set ignition coil air gap with a feeler gauge to OEM spec; install and gap a new spark plug to OEM spec; fill with the correct oil to the full mark.
  3. Supervised start-up and idle check: instructor is present for all starts; students use the correct starting procedure, observe the oil-level/pressure indicator (where equipped), listen for knock or excessive vibration, and record idle RPM with a photo tachometer, comparing to OEM idle specification; engine is shut down safely and the work order is closed out.

SDS binders for gasoline and two-stroke oil, OSHA Hazard Communication (HazCom) standard reference, lockout/tagout tags and hasps, Class B fire extinguisher (for demonstration), grounding straps, approved fuel safety cans, PPE kit (nitrile gloves, safety glasses, face shield), shop ventilation checklistStudents score 80% or higher on a 20-question written quiz covering SDS interpretation, fuel hazard classes, lockout/tagout sequence, and proper PPE selection; hands-on lockout/tagout demonstration graded pass/fail on a step-by-step checklist with zero critical safety steps missed.
2Fuel System Components and Fuel Types12demoStudents will identify every component of a complete small-engine fuel system on at least three different equipment types and explain how ethanol content affects materials, storage life, and jetting requirements.
  1. Instructor narrates a guided disassembly of a walk-behind mower fuel system and a chainsaw fuel system side by side; students label a cut-away diagram with component names, flow direction, and function while the instructor narrates.
  2. Ethanol effects lab: students examine fuel-system components (rubber diaphragms, brass jets, plastic tanks) that have been exposed to E10 and E85 fuels versus 90-octane no-ethanol fuel; groups list observed degradation and report findings to the class.
  3. Students trace fuel flow from tank to combustion chamber on three equipment types (four-stroke mower, two-stroke chainsaw, four-stroke generator) using OEM exploded-view diagrams, then verbally explain each component's function in a round-robin quiz.
Walk-behind mower (running or bench unit), chainsaw (bench unit), small generator, OEM exploded-view parts diagrams for each, cut-away fuel system poster, ethanol-degraded component specimens, E10 and straight-gasoline fuel samples in labeled sealed containers, magnifying glass, nitrile gloves, safety glassesStudents correctly label a blank fuel-system diagram for two different equipment types with 90% accuracy (18 of 20 components correct per diagram) and answer three short-answer questions on ethanol effects with acceptable detail; instructor initials each completed diagram.
3Carburetor Theory and Float Systems14theoryStudents will explain how a float-type carburetor meters fuel across idle, mid-range, and full-throttle circuits and calculate air-fuel ratio changes caused by jet size and float height adjustments.
  1. Lecture and whiteboard session on Bernoulli's principle as it applies to carburetor venturi action; students work three practice problems converting venturi air velocity to pressure drop and explain how that pressure draws fuel through the main jet.
  2. Instructor uses a transparent acrylic carburetor model to demonstrate needle-valve and float operation; students adjust float height on the model, measure it with a vernier caliper against a spec card, and record how raising vs. lowering the float affects fuel level.
  3. Students read a Briggs & Stratton carburetor service bulletin and a Honda GX series carburetor section from the OEM service manual; they annotate fuel circuits on a cross-section diagram and answer an eight-question comprehension check.
Transparent acrylic carburetor model, Briggs & Stratton single-cylinder engine service manual (current edition), Honda GX series service manual, vernier calipers, whiteboard and markers, float-height spec cards for at least three carburetors, cross-section diagram worksheet, scientific calculatorStudents complete a 15-question theory quiz on carburetor circuits, venturi action, float height effects, and air-fuel ratio with a passing score of 80%; float-height measurement on the model is checked against spec — measurement must be within ±0.5 mm of the published value.
4Carburetor Overhaul Lab20labStudents will fully disassemble, ultrasonically clean or solvent-clean, inspect, measure, reassemble, and adjust a float-type carburetor to OEM specifications and document each step in a service record.
  1. Each student is assigned a dirty, gummed carburetor removed from a shop equipment unit; following OEM service manual procedure, students disassemble the carburetor completely, identify each part by name on a parts-layout mat, and photograph the assembly before cleaning.
  2. Students clean all metal parts in the carburetor dip tank or ultrasonic cleaner, blow passages with compressed air wearing face shield, inspect jets with a magnifying glass for obstruction or enlargement, measure float height with calipers, and compare jet size markings against OEM spec — any jet outside spec is flagged for replacement.
  3. Students reassemble the carburetor with a new rebuild kit (gaskets, needle valve, diaphragm if applicable), set the initial idle-mixture screw to OEM turns-out specification, reinstall on the engine, start the engine, and fine-tune idle speed and mixture to achieve smooth idle; students record all measurements and settings on the shop service record form.
Assorted gummed carburetors (Briggs & Stratton, Tecumseh, Honda types), carburetor rebuild kits, dip-tank or ultrasonic cleaner, compressed-air nozzle, magnifying glass, vernier calipers, jet-size reference chart, OEM service manuals for each carburetor, parts-layout mats, service record forms, nitrile gloves, face shield, safety glasses, tachometer or tach/dwell meter, flathead and Phillips screwdrivers, carburetor adjustment tool setCompleted service record signed by student and instructor confirms: all passages clear, float height within OEM spec (±0.5 mm or ±0.020 in), engine starts within three pulls, idle is smooth at OEM rpm ±150 rpm measured with tachometer, no fuel leaks observed during a three-minute run; any failure requires the student to rework the specific step before signing off.
5Diaphragm Carburetors and Primer Systems10practiceStudents will service the diaphragm carburetor and primer-bulb system found on handheld two-stroke equipment, verify diaphragm condition against OEM criteria, and confirm correct fuel delivery after reassembly.
  1. Instructor demonstrates the difference between a float-bowl carburetor and a diaphragm carburetor used in handheld equipment (chainsaws, string trimmers, blowers); students pair up and disassemble a Walbro or Zama-type diaphragm carburetor, identifying pump diaphragm, metering diaphragm, inlet needle, and check valves.
  2. Students inspect each diaphragm by holding it to a light source, checking for cracks, stiffness, or pin-holes; they replace the diaphragm set and gaskets with a new kit and reassemble to OEM torque specifications using an inch-pound torque screwdriver.
  3. Students reinstall the carburetor on a Stihl-type chainsaw (deactivated, spark plug removed, chain brake engaged), connect a hand-operated primer or fuel-line squeeze test to confirm the fuel circuit pulls correctly, then reinstall the spark plug and perform a supervised cold-start and warm idle check, recording results.
Stihl or equivalent chainsaw bench units (chain brake engaged, bar and chain installed but engine not running during disassembly), Walbro and Zama diaphragm carburetor rebuild kits, inch-pound torque screwdriver, Stihl service manual or equivalent OEM reference, primer-bulb inspection specimens, magnifying glass, flashlight, nitrile gloves, safety glasses, hearing protection for start-up, tachometerInstructor observes reassembly sequence and checks torque application; after installation, engine must start within five pulls, run at smooth idle, and show no fuel leaks at primer bulb or carburetor body for a two-minute run; diaphragm inspection decision (replace vs. reuse) must match instructor determination — any discrepancy discussed and documented.
6Fuel Delivery: Pumps, Lines, Filters, and Tanks10practiceStudents will test fuel pump output pressure and volume against OEM specifications, replace fuel lines and filter on two equipment types, and locate and correct one instructor-planted fuel delivery fault.
  1. Students use a low-pressure fuel pump test kit to measure output pressure on a pulse-type mechanical fuel pump; they compare results to OEM spec and record whether the pump passes or fails, then do the same test on a vacuum-operated primer-bulb system using a hand-operated vacuum/pressure pump.
  2. Students replace the in-tank fuel filter and external inline filter on a four-stroke mower and a two-stroke trimmer, cutting fuel lines to the correct length per OEM diagram, routing them without kinks, and securing all connections with the correct clamp type.
  3. Troubleshooting exercise: each bench station has one instructor-planted fault (blocked fuel filter, cracked fuel line, stuck shut-off valve, or collapsed inline screen); students use a diagnostic checklist to isolate the fault, correct it, and verify by running the engine — findings are written on a fault-diagnosis form.
Low-pressure fuel pump test kit with gauge and adapters, hand vacuum/pressure pump, fuel line stock (various diameters), in-tank and inline fuel filters (Briggs, Honda, Stihl types), hose clamps, hose cutter, four-stroke walk-behind mower bench unit, two-stroke trimmer bench unit, OEM service manuals, fault-diagnosis forms, nitrile gloves, safety glasses, drip pansFuel pump pressure reading recorded and within OEM spec ±0.5 psi; fuel line replacement inspected for correct diameter, routing, and clamp seating — zero leaks during a two-minute run; fault correctly identified and documented on form with each step of the diagnostic process described; instructor signs off pass/fail.
7Electronic Fuel Injection (EFI) Fundamentals and Diagnostic Introduction12demoStudents will describe the function of each EFI component on a small-engine platform, interpret a basic fault code from a diagnostic tool, and safely perform a throttle-body inspection and cleaning procedure following OEM steps.
  1. Instructor presents an EFI system overview using a Honda or Kawasaki EFI engine as the training unit, identifying ECU, crank-position sensor, throttle position sensor, MAP/MAF sensor, fuel injector, fuel pressure regulator, and electric fuel pump; students complete a labeled system diagram.
  2. Students connect a manufacturer-approved scan tool or OEM diagnostic app to the training unit, read live data (fuel pressure, injector pulse width, sensor voltages) with the engine running at idle and at fast idle, and record data on a structured observation sheet.
  3. Instructor plants a stored fault code (e.g., sensor out-of-range) in the ECU; students use the scan tool to retrieve the code, look up its definition in the OEM service manual fault-code table, and write a one-paragraph diagnostic report stating the probable cause and the OEM-prescribed next test step.
Honda or Kawasaki EFI small-engine training unit, OEM-approved scan tool or diagnostic tablet with software, OEM EFI service manual with fault-code table, throttle-body cleaning kit (approved solvent spray, clean lint-free rags), structured observation worksheet, labeled EFI diagram handout, nitrile gloves, safety glassesLabeled EFI diagram is 85% accurate (17 of 20 components correctly identified); live-data observation sheet is complete with plausible values matching running engine; written diagnostic report correctly identifies the fault code definition and the first OEM-recommended diagnostic step — scored by instructor on a four-point rubric with a minimum score of 3 required to pass.

#LessonHrTypeObjectiveActivitiesMaterialsCheck
1Electrical Safety, Fundamentals, and Test Equipment12theoryStudents will state Ohm's Law, identify shock and arc-flash hazards on small-engine equipment, apply lockout/tagout, select correct PPE, and demonstrate safe, accurate use of a digital multimeter to measure voltage, current, and resistance.
  1. Instructor-led lecture and whiteboard session: Ohm's Law, series/parallel circuit calculations, and unit conversions (volts, amps, ohms, watts); students solve a 10-problem worksheet and self-grade against an answer key.
  2. Lockout/tagout demonstration on a running mower and generator: students identify all energy-isolation points, apply locks and tags in pairs, then verify zero-energy state before an instructor signs off on each station.
  3. Multimeter lab stations: each student measures battery terminal voltage, tests a known-good resistor, and measures current draw of a small 12 V lamp using a series connection; readings are recorded on a lab sheet and compared to calculated expected values within a stated tolerance.
Digital multimeters (Fluke 115 or equivalent), assorted resistors and 12 V lamps, bench power supplies, lockout/tagout kits (locks, tags, hasps), safety glasses, insulated gloves, Briggs & Stratton Repair Manual (current edition), OSHA 29 CFR 1910.147 reference cardStudent completes the 10-question Ohm's Law worksheet with 80% or better; instructor verifies each lockout/tagout application on a signed checklist—any missed energy-isolation point requires immediate remediation and re-check before the student may proceed.
2Reading Wiring Diagrams and Circuit Tracing10theoryStudents will correctly interpret OEM wiring diagrams for at least three different equipment platforms, identify wire color codes and connector types, and trace a complete circuit from power source to ground on a bench harness.
  1. Guided reading exercise: students receive three OEM wiring diagrams (Briggs & Stratton engine, Honda GXV-series, Stihl battery-powered tool) and individually label each symbol, wire color, connector designation, and ground point, then compare answers in a small-group review.
  2. Instructor demonstrates circuit tracing on a partially assembled bench wiring harness using the 'power-side/ground-side' discipline; students then repeat the trace on a second harness in pairs, recording each component's function on a circuit-map worksheet.
  3. Fault-finding introduction: instructor inserts one open-circuit fault and one short-to-ground fault into bench harnesses; students use their diagrams and a multimeter to locate each fault, document the test sequence, and describe the repair—results checked against an answer card.
Printed and digital OEM wiring diagrams (Briggs & Stratton, Honda, Stihl current service manuals), bench wiring harnesses with installed fault switches, digital multimeters, circuit-map worksheets, colored pencils for diagram annotation, safety glassesCircuit-map worksheet scored by instructor: student must correctly identify 100% of ground points and 80% of all labeled components; both faults must be located and documented with the correct test procedure—one missed fault requires re-trace before advancing.
3Ignition System Theory, Testing, and Service18labStudents will diagnose ignition system faults—including a failed coil, fouled spark plug, worn flywheel key, and defective kill switch—on two-stroke and four-stroke engines by performing gap measurement, spark testing, coil air-gap setting, and resistance testing, then complete the correct repair.
  1. Instructor demonstration of solid-state ignition operation using a cutaway engine and oscilloscope display; students identify the primary winding, secondary winding, flywheel magnet, and module, then record the firing sequence in their lab notebooks.
  2. Rotating lab stations (pairs): Station A—remove, inspect, gap-check, and reinstall a spark plug to OEM specification using a feeler gauge; Station B—test coil primary and secondary resistance with a multimeter and compare to OEM spec sheet; Station C—set coil air gap on a disassembled engine using a business-card shim to OEM specification; Station D—test kill-switch continuity in RUN and STOP positions.
  3. Seeded-fault exercise: each student receives an engine with one of four pre-installed faults (wrong spark-plug gap, open kill switch, mis-set coil air gap, sheared flywheel key); student must diagnose, document on a fault-report form, repair, and verify correct ignition spark with an inline spark tester before the instructor signs off.

4Battery Service and Charging Systems14labStudents will perform state-of-charge testing, load testing, charging, and safe disposal procedures on lead-acid and AGM batteries, and will test AC stator output, rectifier/regulator function, and DC charging voltage on a running small engine to OEM specification.
  1. Battery service rotation: each student measures open-circuit voltage, performs a carbon-pile load test per battery manufacturer specification, records results on a condition log, and connects a smart charger—instructor checks polarity and clamp connections before energizing; worn-out batteries are tagged for recycling and students complete a simulated hazardous-materials disposal form.
  2. Charging system bench test: with the engine running at the RPM specified in the service manual, student probes stator AC output terminals with a multimeter set to AC volts, records reading, then checks DC charging voltage at the battery terminals; results are compared to OEM specification and recorded.
  3. Rectifier/regulator diode test: student uses the multimeter diode-test function to check each diode in a removed rectifier/regulator, records forward-bias and reverse-bias readings, and determines whether the unit passes or fails per instructor-provided acceptance criteria based on OEM specifications.
Lead-acid and AGM batteries (various states of health), carbon-pile load tester, smart battery charger, digital multimeters, small engine with charging system (Honda GX or Briggs & Stratton with alternator), tachometer, OEM service manuals, simulated hazardous-materials disposal forms, battery condition logs, PPE (safety glasses, face shield, acid-resistant gloves, apron)Charging system test sheet reviewed by instructor: stator AC output, rectifier diode readings, and DC charging voltage must all be recorded with units and compared to spec—pass requires all three tests completed with readings within 10% of OEM specified range; any unrecorded measurement or wrong meter function requires immediate re-test.
5Starting Circuits: Starters, Solenoids, and Interlock Systems14labStudents will diagnose and repair starting-circuit faults—including a failed solenoid, open interlock switch, dragging starter motor, and corroded cable connection—by performing voltage-drop testing, continuity testing, and current-draw measurement on a 12-volt starting system.
  1. Voltage-drop lab: with the engine disabled (fuel removed, spark plug wire grounded), student cranks the starter and simultaneously measures voltage drop across each cable and connection in the starting circuit; readings are recorded and compared to the industry-accepted threshold for acceptable voltage drop, with any over-spec drop flagged for repair.
  2. Interlock switch mapping exercise: using the OEM wiring diagram for a riding mower, student locates every seat, blade-engagement, and brake/clutch safety interlock switch on the actual machine, tests each for proper operation with a multimeter, and completes a switch-condition matrix showing open/closed state for each operational mode (seated/unoccupied, blade on/off, brake set/released).
  3. Seeded-fault starting circuit: instructor pre-installs one of three faults (open solenoid coil, corroded battery cable, stuck-open seat switch); student performs a systematic diagnosis using voltage-drop and continuity tests, documents the test sequence, and makes the repair; start function is verified before instructor signs the repair order.
12 V riding mower or engine test stand with electric start, digital multimeters, DC clamp ammeter, jumper wires with fused leads, solenoid test light, OEM wiring diagrams, corrosion-treatment spray, terminal cleaning brushes, replacement solenoid and interlock switches, safety glasses, insulated glovesCompleted repair order reviewed by instructor: voltage-drop readings at each point recorded, fault correctly identified with supporting test data, repair made and start function verified—pass requires correct fault identification supported by measured data; a diagnosis not supported by recorded measurements is not accepted.
6Lighting, Accessory Circuits, and Electronic Controls11demoStudents will trace, test, and repair faults in lighting and accessory circuits—including a blown fuse, open ground, burned lamp socket, and faulty module connector—and will describe the function of common electronic control units found on OEM equipment.
  1. Instructor-led teardown and explanation of a Honda or Stihl battery-powered tool electronic control board: students label the control inputs (trigger, battery pack, temperature sensor) and outputs (motor drive, LED indicator) on a printed diagram, then discuss why connector cleanliness and correct reassembly torque matter for reliable operation.
  2. Lighting circuit diagnosis lab: each student receives a bench lighting harness with one seeded fault (blown fuse, open ground wire, corroded lamp socket, or broken connector pin); student diagnoses with multimeter, documents the test sequence, makes the repair, and verifies lamp function.
  3. Fuse and connector service practice: students remove and inspect blade fuses using a fuse puller and test lamp, then practice proper installation technique for push-to-seat and locking-tab connectors using OEM connector service kits; instructor checks each completed connection for full engagement and correct orientation.
Bench lighting harnesses with fault switches, OEM connector service kits (Honda and Briggs & Stratton terminal removal tools, replacement terminals), fuse puller, assorted blade fuses, test lamp, digital multimeters, printed circuit diagrams, battery-powered tool control board display unit (non-operational training aid), safety glassesInstructor inspects completed connector and lamp repair: lamp must illuminate on first key-on, fuse must be correct rating, and connector must audibly or tactilely click into full engagement—any loose connection or wrong-rated fuse is a fail requiring immediate redo.
7Integrated Electrical Diagnosis Practicum8practiceStudents will independently diagnose a multi-fault electrical system—spanning ignition, charging, and starting circuits—on a complete small engine or power equipment unit using only OEM service documentation, record findings on a professional repair order, and complete all repairs within a defined time limit.
  1. Pre-lab briefing: student reviews OEM wiring diagram for the assigned unit (Briggs & Stratton, Honda, or Stihl platform), prepares a written test plan identifying which circuits to test first and what measurements to take, and presents the plan verbally to the instructor for approval before touching any tool.
  2. Timed diagnosis and repair session (approximately 5 hours): student locates and repairs up to three pre-installed faults across different electrical sub-systems, documenting each measurement, comparison to spec, diagnosis conclusion, and repair action on a standard repair order form; instructor observes but does not coach.
  3. Post-repair verification and debrief: student performs a full operational check of all repaired circuits, demonstrates correct start/run/charge function, and presents the completed repair order to the instructor; the instructor asks three follow-up diagnostic questions (e.g., 'What would you check next if the charging voltage were still low after your repair?') and student answers verbally.
Complete power equipment unit with pre-installed multi-system faults (instructor-prepared), OEM service manual for that unit, digital multimeter, inline spark tester, carbon-pile load tester or clamp ammeter, standard shop repair order forms, torque wrench, basic hand tools, PPE (safety glasses, gloves)Repair order scored on a rubric (50 points total): correct diagnosis with supporting measurements 20 pts, all repairs completed and verified functional 20 pts, professional documentation quality 10 pts—pass is 40/50 (80%); failure on any safety step (working on live circuits without authorization, missing PPE) is an automatic fail requiring the full practicum to be repeated.

3Riding Mower Hydrostatic and Gear Transmissions, Steering, and Brake Systems12labStudents will inspect fluid levels and condition in a hydrostatic transmission, perform a brake adjustment, and diagnose a simulated transmission-output fault using OEM diagnostic procedures.
  1. Fluid service drill: students locate the hydrostatic transmission reservoir on an assigned riding mower, check fluid level and color against OEM specs, drain and refill to the OEM-specified fluid type and quantity, and bleed air from the system per the service manual purge procedure.
  2. Brake adjustment exercise: students measure brake pedal free-travel, locate the adjusting rod or cam, adjust to OEM specification, and perform a static brake-hold test documenting results on a repair order.
  3. Fault-finding scenario: instructor installs one of three pre-set faults (low fluid, bypassing pump, stuck bypass valve); students follow the OEM symptom-to-cause chart, measure outputs with the appropriate tools, identify the fault in writing, and propose a documented repair.
Riding mower with hydrostatic transmission, OEM service manual (hydrostatic section), correct hydraulic/transmission fluid per OEM spec, drain pan, fluid transfer pump, brake adjustment tools, dial indicator, torque wrench, repair order forms, instructor fault-set kit (pre-staged faults)Student completes a repair order with correct fluid type, quantity, and purge steps documented, brake free-travel within OEM range, and written fault identification matching the instructor-installed fault. Pass = repair order complete and accurate with no fluid type errors and correct fault identification; incorrect fluid selection is an automatic fail requiring repeat.
4Portable Generator Systems: Load Circuits, AVR, and Output Diagnosis18labStudents will measure generator AC output voltage, frequency, and load regulation, diagnose a no-output or low-voltage condition using a digital multimeter and OEM wiring diagram, and replace or adjust the automatic voltage regulator as required.
  1. Output measurement lab: with the generator running at no-load, students connect a true-RMS multimeter to the output receptacle, record voltage and frequency, then apply a resistive test load to rated wattage and record voltage under load, comparing results to OEM specification and calculating voltage regulation percentage.
  2. AVR diagnosis simulation: instructor pre-sets one of three faults (disconnected AVR lead, failed capacitor, open rotor circuit); students use the OEM wiring diagram to follow a systematic test sequence—field winding resistance, brush-to-slip ring continuity, capacitor test—and identify the fault in a written diagnosis.
  3. AVR replacement or adjustment: students remove and replace an AVR on a designated generator, connect leads per the wiring diagram, start the unit, and trim output voltage to OEM specification using the voltage adjust potentiometer, documenting before and after voltage readings.
Portable generators (Honda EU-series or equivalent, Briggs & Stratton generator), true-RMS digital multimeter, clamp-on ammeter, resistive load bank or test load resistors, OEM wiring diagrams, replacement AVR units, capacitor ESR tester, brush set, torque screwdriver, safety barrier and signage for live-output work, PPE (rubber-insulated gloves, eye protection)Student submits a completed diagnosis report showing measured voltage and frequency at no-load and full-load, calculated voltage regulation, correct fault identification matching instructor pre-set, and final output voltage within OEM specification after AVR adjustment. Pass = all values within OEM tolerance and fault correctly named; live-conductor contact without PPE is an automatic fail.
5Chainsaw Anatomy, Chain and Bar Service, and Chain Brake Inspection16labStudents will select a chain of correct pitch, gauge, and drive-link count for an assigned bar, install and tension it to OEM specification, file each cutter to the manufacturer's specified angle and depth-gauge setting, and verify chain brake engagement and stopping time.
  1. Chain selection exercise: given a bar specification card and a selection of chains with mixed pitch and gauge markings, students use the OEM Stihl or equivalent cross-reference chart to identify the correct chain, record the pitch, gauge, and drive-link count on a parts worksheet, and explain the consequence of an incorrect selection in writing.
  2. Chain installation and tensioning lab: students mount the bar, install the chain with cutters facing the correct direction, adjust the tensioner until the drive links seat in the bar groove and the chain can be pulled around without binding, torque the bar nuts to OEM specification, and perform the snap-back test.
  3. Chain filing and brake check station: using a round file, flat file, and depth-gauge tool, students file each cutter to the OEM specified top-plate angle and side-plate angle and set depth gauges to OEM specification; students then test chain brake engagement by simulating a kickback wrist motion on a stationary saw and confirm the brake band locks the sprocket, documenting results.
Stihl or equivalent chainsaws (multiple bar lengths), assorted replacement chains (mixed pitch/gauge for selection exercise), round files (correct diameter per chain pitch), flat file, depth-gauge tool and joint, bar-and-chain oil, OEM Stihl service manual and chain catalog, torque wrench, chain break inspection checklist, chainsaw chaps, cut-resistant gloves, face shield, hearing protectionInstructor measures three randomly selected cutters with a digital angle gauge and depth-gauge tool; all three must be within ±1° of OEM angle and depth gauge within OEM tolerance. Chain tension passes the snap-back test, and brake engagement is confirmed at the inspection checklist. Pass = all cutter measurements in spec, chain tension correct, and brake functional; a single out-of-spec cutter requires refiling and re-check.
6Chainsaw Fuel and Oiler Systems, Anti-Vibration Service, and Two-Stroke Mixture9demoStudents will mix two-stroke fuel to the OEM-specified ratio, clean or replace the chainsaw oiler filter and adjust oiler output, and inspect and replace anti-vibration (AV) mounts to OEM condition standards.
  1. Fuel-mix demonstration and practice: instructor demonstrates measuring and mixing two-stroke engine oil at the OEM-specified ratio for the assigned saw using calibrated containers; students then each mix a one-liter batch, label the container with ratio and date, and record the calculation showing oil volume in milliliters.
  2. Oiler service: students remove the chainsaw oiler cover, extract and inspect the oil-pickup filter, clean or replace as condition requires, reinstall, fill the reservoir, run the saw briefly over white cardboard, and observe oil throw pattern to confirm oiler delivery, adjusting the output screw as needed per OEM procedure.
  3. AV mount inspection and replacement: using the OEM wear limit specifications, students measure AV buffer deflection or inspect for cracking/collapse, compare to OEM go/no-go criteria, and replace any mount that fails inspection, torquing fasteners to OEM specification.
Chainsaws with removable oiler covers, two-stroke engine oil (OEM-specified brand/grade), calibrated measuring containers, fuel cans, white cardboard for oiler pattern test, replacement oiler filters, replacement AV mounts, torque wrench, OEM Stihl service manual (oiler and AV sections), PPE (eye protection, gloves)Student presents a labeled fuel-mix container with correct ratio written on it and demonstrates the calculation; instructor verifies oil-throw pattern on cardboard is continuous, and AV mount condition is documented on an inspection sheet with accept/reject decisions. Pass = ratio calculation correct, oiler pattern continuous, and all AV decisions matching instructor key; an incorrect mix ratio requires remixing.
7Integrated Service Job: Diagnosis, Repair Order, and Quality Inspection Across All Three Equipment Types6practiceStudents will independently diagnose a customer-complaint scenario on each of the three equipment categories, write a complete repair order with parts and labor estimate, perform the repair, and pass a quality inspection.
  1. Three-station timed rotation: each student works through a mower station (e.g., no self-propel drive), a generator station (e.g., voltage drops under load), and a chainsaw station (e.g., chain does not advance oil) — each with a printed customer complaint card — diagnosing the fault, listing root cause and corrective action on a repair order, and performing the repair within the allotted time.
  2. Parts look-up and costing: for each repair, students use the OEM parts catalog (print or digital) to identify the correct part number, look up list price, and calculate a total estimate including labor at a standard shop rate provided on the scenario card, entering all figures on the repair order form.
  3. Peer and instructor quality walk: after repairs, students pair up for a peer review using an OEM inspection checklist, then the instructor performs a final quality inspection, measuring or testing each repair outcome against the specification documented on the repair order.
One each: walk-behind or riding mower, portable generator, and chainsaw with pre-installed faults (instructor fault kit), OEM service manuals (Briggs, Stihl, Honda), OEM parts catalogs (print or digital access), repair order forms, shop-rate card, inspection checklists, all standard hand and power tools from previous lessons, PPEInstructor scores each completed repair order on a rubric: correct fault identification (25%), correct parts number and estimate (25%), repair meets OEM specification on final measurement (40%), and LOTO/PPE compliance throughout (10%). Pass = 80% total with no zero in the LOTO/PPE category; a zero in LOTO/PPE is an automatic fail of the entire lesson regardless of other scores.

#LessonHrTypeObjectiveActivitiesMaterialsCheck
1Project Planning, Equipment Selection, and Pre-Teardown Assessment18labGiven a faulted unit selected from the shop equipment pool, the student produces a signed safety plan, a completed customer intake work order, and a documented pre-teardown assessment that identifies all suspected fault systems before any disassembly begins.
  1. Students choose or are assigned a faulted unit (walk-behind mower, string trimmer, generator, chainsaw, or ATV) and retrieve its OEM service manual; they complete a customer intake form recording all reported symptoms, hours of service if known, and visible external condition, then photograph the unit from all four sides and record the model and serial number.
  2. Working through the OEM diagnostic flowchart, students perform a systematic no-disassembly assessment — compression test, spark test, visual fuel system check, electrical continuity checks — recording every result on a standardized diagnostic worksheet and circling each suspected fault system (engine, fuel, ignition, charging, drive) before committing to a disassembly plan.
  3. Each student writes a one-page project plan listing the repair sequence, all required special tools, estimated parts list with placeholder costs, and a safety checklist confirming lockout/tagout points, required PPE for each phase, and waste disposal method for fuel and oil; the instructor reviews and signs the plan before teardown is authorized.
Shop equipment pool (mowers, trimmers, generators, chainsaws, ATVs with documented faults), OEM service manuals, compression gauges, spark testers, digital multimeters, digital calipers, camera or phone for documentation, shop work order forms, diagnostic worksheets, PPE (safety glasses, nitrile gloves, hearing protection), lockout/tagout kitInstructor reviews the pre-teardown diagnostic worksheet and project plan; competence is confirmed when all required fields are complete and accurate, at least two suspected fault systems are identified with supporting measurement data, and the safety plan correctly identifies all lockout/tagout points — all three elements must be satisfactory before teardown is authorized (pass = instructor sign-off, no incomplete fields).
2Disassembly, Precision Measurement, and Parts Evaluation30labFollowing the approved project plan, the student safely disassembles all involved systems, records precision measurements for every wear component against OEM specifications, and produces a parts disposition list that correctly classifies each component as reuse, resurface, or replace.
  1. Students perform a controlled, sequenced disassembly using the OEM service manual torque and sequence references, photographing assemblies before removal, tagging all fasteners and small parts in labeled containers, and applying lockout/tagout at every stage; the instructor spot-checks PPE compliance and component organization at least once during this lesson block.
  2. Students measure all critical wear components — cylinder bore diameter, piston ring end gap, crankshaft journal diameter, valve stem clearance, armature air gap, carburetor float height — using feeler gauges, outside micrometers, and telescoping gauges as appropriate, recording every measurement on a two-column spec sheet (OEM spec vs. measured) and calculating the deviation.
  3. Using the completed spec sheet, students compile a parts disposition list and prepare a revised parts order with actual part numbers pulled from the OEM parts lookup, then update the work order with the final labor estimate; the instructor verifies measurement technique by observing the student take at least three measurements live and asking the student to state the OEM specification from memory or by correctly locating it in the service manual.
OEM service manuals and parts microfiche/online lookup, outside micrometers (0–1 in, 1–2 in), telescoping gauges, feeler gauge sets, bore gauges or small-hole gauges, digital calipers, torque wrenches, impact tools, parts cleaning tank with approved solvent, parts trays, labeling tape, two-column spec sheets, revised work order forms, PPEInstructor reviews the completed two-column spec sheet and parts disposition list; all measurements must be recorded with correct units, each measurement must be compared to the OEM spec with a clear pass/replace notation, and measurement technique must be observed as correct on at least three live checks — pass requires all measurements recorded correctly and technique rated satisfactory by the instructor with no unsafe practices observed.
3Repair or Rebuild, Reassembly, and Return-to-Service Inspection42labThe student completes all approved repairs or part replacements, reassembles the unit to OEM specifications using correct torque values and sequences, and verifies that the unit passes a complete return-to-service functional and safety inspection before the engine is started.
  1. Students install all replacement parts — which may include piston rings, valves and valve seals, carburetor rebuild kit, ignition module, rewind starter, belts, or blades depending on the unit — following OEM assembly sequences, applying thread-locking compound or gasket sealer only where the manual specifies, and torquing all fasteners to spec in the correct sequence; the instructor verifies torque wrench use on at least one critical fastener group (head bolts or flywheel nut) before the student proceeds past that step.
  2. Students complete a pre-start return-to-service checklist covering: fuel system leak check, spark plug gap set to spec, air filter installed, blade torque or chain tension within spec, all guards and covers secured, oil at correct level, and battery or charging system voltage within range; they then perform a first-start sequence per OEM procedure, observe for abnormal smoke, noise, or vibration, and set governed no-load speed using a digital tachometer, recording the result against the OEM specification.
  3. Where equipment type permits, students perform a brief functional load test — mowing a grass strip, cutting a wood round with a chainsaw on a bench vise, or running a generator under a resistive load — and complete the final work order entry with actual labor hours, parts used, all measurements, and test results; the complete work order packet (intake form, diagnostic worksheet, spec sheet, parts list, inspection checklist, and final test data) is compiled into the project portfolio binder.
Replacement parts sourced per approved parts order, OEM service manuals, torque wrenches (in-lb and ft-lb), thread locker and gasket sealer per OEM spec, digital tachometer, digital multimeter, resistive load bank or test load for generators, PPE (add face shield for starting and blade work), return-to-service checklist forms, final work order forms, project portfolio bindersInstructor witnesses the first start and performs a random spot-check of at least two torqued fasteners with a calibrated torque wrench; pass requires: no fluid leaks, governed no-load speed within ±200 RPM of OEM spec (or OEM-stated tolerance where tighter), all guards in place, completed return-to-service checklist signed, and the full documentation packet assembled — any safety deficiency is an automatic fail requiring correction before the oral defense is scheduled.
4Oral Defense and Professional Documentation Review18labThe student presents and defends the completed project to an evaluator panel, accurately explaining the diagnostic rationale, each repair decision, the safety measures applied, and the final test results, while demonstrating that all documentation meets professional shop standards.
  1. Each student delivers a structured 10-minute presentation (no slides required; the work order packet and the repaired unit serve as the visual aid) walking the panel through: the initial symptoms, the diagnostic process and evidence, the OEM specifications that guided part replacement decisions, the reassembly and torquing procedure, and the final test data — the panel evaluates clarity, accuracy, and ability to cite the service manual.
  2. The evaluator panel asks a minimum of five technical questions drawn from the project work, such as: 'What would happen if the ring end gap were below the minimum specification?', 'Where exactly did you apply lockout/tagout on this unit and why?', or 'The spec says intake valve clearance is 0.006 in — what tool did you use and how did you set it?' — student answers are scored on a rubric for technical accuracy and safety reasoning.
  3. The panel reviews the project portfolio binder for completeness, legibility, and professional format; any discrepancy between the documentation and the observed unit (e.g., a part listed as replaced that has not been replaced) is noted and the student must explain or correct it on the spot — final portfolio score and oral score are recorded and returned to the student with written feedback before the externship begins.
Completed repaired unit, project portfolio binder, OEM service manual (student may reference during defense), oral defense rubric, panel score sheets, evaluator feedback formsOral defense rubric scored by the panel on four domains — diagnostic accuracy, technical decision-making, safety application, and documentation quality — each domain scored 1–4; pass requires a minimum score of 3 (satisfactory) in every domain with no domain scored below 2; a score of 2 in any domain triggers a one-time re-defense of that domain within five school days.
Assessments

Capstone Repair Project — Functional Unit and Work Order PacketProject60%The repaired unit must start and operate within OEM no-load speed specification, pass the return-to-service checklist with no open items, and contain no fluid leaks or unguarded moving parts; the work order packet must include all required documents (intake form, diagnostic worksheet, two-column spec sheet, parts disposition list, revised estimate, final invoice, and return-to-service checklist) with all fields complete and all measurements recorded with correct units — any safety deficiency is an automatic fail.The student submits the physically repaired and functionally tested unit together with the complete shop work order packet as evidence of integrated technical competence; the instructor verifies the unit against the return-to-service checklist and reviews the packet for accuracy, completeness, and professional presentation. This assessment maps to EETC exam domains covering engine service, fuel system service, ignition service, and electrical service, as well as OEM certification requirements for correct use of service documentation.
Meets specification · Within estimate · Workmanship · Safety · Documentation
Project Portfolio BinderPortfolio20%All six required documents must be present, legible, and internally consistent; every measurement entry must include the OEM specification, the measured value, the deviation, and a clear disposition decision; parts entries must include OEM part numbers; labor entries must reflect actual time recorded — portfolio is scored on a 24-point rubric (six documents × 4 points each) and a minimum of 18 out of 24 points is required to pass.The portfolio binder is a professional documentation record that a working shop could hand to a customer or auditor, demonstrating that every step of the repair was planned, measured, and verified against OEM data; it is evaluated for technical accuracy, completeness, and professional format. This assessment maps to EETC and OEM certification emphasis on correct use of service manuals, parts documentation, and written communication skills required of a working technician.
Completeness · Organization · Evidence quality
Oral DefenseOral / panel20%Minimum score of 3 out of 4 (satisfactory) in all four rubric domains — diagnostic accuracy, technical decision-making, safety application, and documentation quality — with no domain scored below 2; a single domain scored at 2 allows one re-defense of that domain within five school days, but a domain scored at 1 (unsatisfactory) on first attempt requires the full defense to be repeated after remediation.The oral defense is a 10-minute structured presentation followed by a minimum of five panel questions; it requires the student to explain every technical decision made during the project, cite OEM specifications from memory or by correctly locating them in the service manual, and demonstrate clear understanding of how OSHA safety requirements — including lockout/tagout and PPE selection — were applied. This assessment maps to EETC oral and practical competency standards and to OEM certification expectations for technicians who must communicate diagnostic findings to service advisors and customers.

#LessonHrTypeObjectiveActivitiesMaterialsCheck
1Exam Landscape, Self-Assessment, and Study Planning8theoryStudents map the EETC and selected OEM exam structures to their own scored diagnostic results and produce a written, prioritized study plan.
  1. Review the EETC candidate guide and OEM technician certification overviews to chart each exam's content domains, question formats, and time limits on a single comparison matrix.
  2. Complete a 60-question diagnostic practice set drawn proportionally from all EETC content domains; score immediately, then categorize every missed item by domain and sub-topic on a personal gap chart.
  3. Using the gap chart, write a two-week study plan that assigns daily review topics, reference materials (OEM service manuals, EETC study guide), and measurable daily goals, then share with the instructor for feedback.
EETC candidate handbook, Briggs & Stratton MST and OHV service manuals, Stihl and Honda technician training workbooks, printed diagnostic practice set, gap-analysis worksheet template, highlightersInstructor reviews each student's gap chart and study plan for completeness and accuracy; plan must correctly identify at least three specific weak domains and cite the correct reference pages for each — pass requires a complete, instructor-approved plan.
2Domain Deep-Dive: Engine, Fuel, and Electrical Systems Review18practiceStudents answer timed domain-specific practice banks and perform hands-on bench exercises to reinforce correct diagnostic reasoning in the three highest-weighted EETC exam areas.
  1. Work through three timed practice banks (engine systems, fuel systems, electrical systems — approximately 40 questions each) in rotating 75-minute sessions; after each bank, pair with a partner to explain the reasoning behind every wrong answer using the relevant OEM service manual page.
  2. Complete six bench exercises — one compression test and valve clearance check, one carburetor teardown and main jet sizing identification, one ignition system primary/secondary resistance measurement, one fuel system flow-and-pressure test, one charging system output verification, and one starter motor current-draw test — recording actual vs. specification values and stating pass/fail with justification.
  3. Participate in instructor-led whiteboard case studies: given a written symptom description (e.g., 'Briggs 625EX cranks but will not start, spark confirmed'), students vote on root cause using individual dry-erase boards, then the group traces the correct diagnostic path step-by-step using the OEM flowchart.
Shop engines (Briggs & Stratton OHV single-cylinder, Stihl 2-stroke, Honda GX series), compression gauge, digital multimeter, ignition tester, carburetor rebuild kit, fuel pressure gauge, battery load tester, OEM service manuals for each platform, printed practice question banksStudents must score 75% or higher on each of the three domain practice banks; bench exercise data sheets must show correct go/no-go decisions on all six tasks with spec citations — any score below 75% or incorrect bench call triggers same-day targeted remediation before the next session.
3Equipment-Specific and OEM Certification Review10demoStudents demonstrate the service procedures and documentation practices most commonly tested on Briggs & Stratton, Stihl, and Honda OEM technician assessments.
  1. Instructor demonstrates and students then independently perform three OEM-specific procedures under observation: a Briggs & Stratton engine oil fill and break-in inspection using the MST checklist, a Stihl chain saw bar-and-chain setup with correct chain pitch and gauge verification, and a Honda GX governor adjustment to specified no-load RPM — each procedure is timed to match realistic exam scenario pacing.
  2. Work through OEM warranty documentation exercises: given a hypothetical customer complaint and repair scenario, students complete a sample warranty claim form for each manufacturer, correctly identifying the failure mode, labor operation code category, and parts required — instructor checks for accuracy against OEM policy guidelines.
  3. Conduct a peer-teaching rotation: each student selects one OEM-specific topic from their gap chart (e.g., Stihl STIHL-tec chain oil specification, Honda automatic choke operation, Briggs & Stratton Magnetron ignition timing) and delivers a five-minute explanation with a visual aid, fielding two questions from peers.
Briggs & Stratton MST service manual and warranty documentation samples, Stihl workshop manual and chain specification chart, Honda GX series service manual, tachometer, torque wrench, sample OEM warranty claim forms, timerAll three OEM procedures must be completed correctly and within time; instructor uses a go/no-go checklist with a minimum of 80% of steps performed correctly and in the right sequence — warranty documentation must contain zero errors in failure-mode classification to pass.
4Full-Length Mock Certification Exams and Final Debrief9practiceStudents complete timed, full-length mock exams that replicate EETC and OEM exam conditions, then analyze results to confirm readiness or complete targeted last-minute remediation.
  1. Sit a full-length timed EETC mock exam (question count and time limit set to match the current EETC exam format) under strict exam conditions — no notes, no phones, answers recorded on a bubble sheet; upon completion, score the exam and receive a domain-by-domain score report.
  2. Sit a condensed OEM technician practice assessment combining Briggs & Stratton, Stihl, and Honda question sets; upon completion, compare scores against OEM passing thresholds and annotate the answer key with the specific manual page that supports each correct answer.
  3. Attend a structured group debrief: instructor projects the ten most commonly missed items from the class mock results, walks through the correct reasoning for each, and students write a one-paragraph 'exam-day strategy note' capturing their two biggest remaining risk areas and one concrete action for each — plans are submitted to the instructor as the final course artifact.
Printed full-length EETC mock exam booklets and bubble sheets, OEM combined practice assessment printouts, pencils, clock or timer visible to all students, answer keys with manual-page citations, domain score report templateStudents must score at a level meeting or exceeding the program's readiness benchmark (set at or above the EETC published passing standard) on the mock EETC exam; students scoring below the benchmark complete an instructor-directed remediation session and a targeted 20-question re-test before being cleared to register for the credentialing exam.
