Common problems

Engine cranks but will not start — spark plug is wet
Cause: Overchoking
Engine cranks but will not start — spark plug is dry
Cause: Leaking carburetor mounting gaskets
Engine starts hard or will not start
Cause: Physical damage to the AC generator; check the Rotor for contact with the Stator
The engine cranks but will not start
Cause: Vehicle fuel shutoff valve closed
Fix: Open valve, if so equipped.
Voltage & frequency are both high or low
Fix: Check engine governor (Test 2)
The engine will not crank
Cause: System control fuse blown
Fix: Replace fuse.
The engine starts, but shuts down when the Start/Stop switch is released
Cause: Low engine oil level
Fix: Check oil and add oil, as needed.
Generator produces zero voltage or residual voltage (5-12 VAC)
Fix: Perform fixed excitation / rotor amp draw (Test 4); test stator DPE winding (Test 7); check sensing leads / power windings (Test 8); check brush leads (Test 9); check brushes & slip rings (Test 10); check rotor assembly (Test 11); check insulation resistance (pages 13-14); repair or replace bad components; replace voltage regulator; reset to "ON" or replace if bad
Engine will not crank
Cause: Bad 7.5 amp fuse; bad battery or cables; no power supply to engine circuit board; bad start/stop switch; no power supply to wire 56; bad starter contactor relay; bad starter contactor; defective starter motor; mechanical binding of the engine or rotor
Fix: Replace fuse; recharge or replace battery, clean, repair or replace bad cable(s); check wiring and wire connections, repair, reconnect or replace bad wires as required; replace defective switch; replace engine controller circuit board; replace bad starter contactor relay; replace starter contactor; replace starter motor if defective; check for mechanical binding of the engine or rotor; go to Problem 10

Cause: Defective Start/Stop switch
Fix: Replace switch.
Priming function does not work (gasoline models)
Cause: Defective primer switch; defective fuel pump
Fix: Replace bad switch; replace fuel pump if defective; try cranking the engine (Test 18); test primer switch (Test 19); check fuel pump operation (Test 20); go to Problem 6

Cause: Low oil level; bad oil pressure switch; bad oil temperature switch; bad start/stop switch; bad wire 18
Fix: Replenish oil; replace bad switch; repair or replace; replace bad switch; go to Problem 8; if oil pressure is low, find the cause and correct; if oil temperature is high, determine the cause and correct
Engine starts hard and runs rough (LP units)
Cause: Low LP pressure; bad spark plug; bad ignition coil; incorrect valve adjustment; sheared flywheel key; engine/cylinder leak down or compression problem; fuel regulator and carburetor problem
Fix: Replenish fuel supply; clean and regap or replace spark plug; replace coil; adjust valves; check flywheel key (see Test 34); repair or replace as necessary; check fuel regulator and carburetor

Procedures

Adjust Choke Solenoid adjustment

Loosen screws retaining choke solenoid to its bracket.
Slide choke solenoid in slotted holes to adjust axial movement of solenoid plunger.
Adjust until, with choke plate closed, solenoid is bottomed in its coil.
Tighten the two screws; verify plunger and linkage move freely.

Adjust Engine Governor adjustment

Tools: pliers

Loosen the governor clamp bolt.
Hold governor lever at wide open throttle and rotate governor shaft fully clockwise.
While holding, tighten governor clamp bolt to 70 inch-pounds (8 N-m).
Start engine and let it stabilize.
Turn adjuster nut to obtain 62 Hertz.
Check AC voltage; adjust voltage regulator if needed.

Adjust Valve Clearance adjustment

Tools: 10mm allen wrench, feeler gauge, crow's foot

Loosen the rocker arm jam nut.
Use a 10mm allen wrench to turn the pivot ball stud while checking clearance with a feeler gauge.
When clearance is correct, hold the pivot ball stud and tighten the jam nut with a crow's foot.
Recheck valve clearance to be sure it did not change.

Adjust Voltage Regulator adjustment

Set frequency at 62.5 Hertz with no load on generator.
Slowly turn the voltage adjust pot until 124 VAC is measured.
If voltage is not adjustable, refer to troubleshooting.

Adjusting Valve Clearance adjustment

⚠ Hold the rocker arm jam nut in place as the pivot ball stud is turned.

⚠ Start all four screws before tightening.

Tools: Feeler gauge, 10mm allen wrench, #2 or #3 Phillips screwdriver, Large socket and socket wrench

Make sure the engine is cool and at 60 deg to 80 deg F.
Remove spark plug wires and position them away from plugs.
Remove spark plugs.
Rotate the engine clockwise with a socket on the flywheel nut to bring the piston to Top Dead Center of its compression stroke.
Remove the four screws attaching the valve cover.
Loosen the rocker jam nut and use a 10 mm allen wrench to turn the pivot ball stud while checking clearance with a feeler gauge.
When clearance is correct, hold the pivot ball stud and tighten the rocker arm jam nut to 174 in/lbs.
Recheck valve clearance after tightening.
Install a new valve cover gasket and re-attach the valve cover.
Install spark plugs and re-attach the spark plug wires.

Check and Adjust Valve Clearance adjustment

Tools: 10mm allen wrench, feeler gauge, crow's foot torque wrench

Adjust valve clearance with engine at room temperature, piston at TDC of compression stroke.
Loosen rocker arm jam nut, use 10mm allen wrench to turn pivot ball stud while checking clearance with feeler gauge.
Set intake valve clearance 0.002-0.004 in and exhaust valve clearance 0.002-0.004 in.
Hold pivot ball stud with allen wrench and tighten rocker arm jam nut to 174 inch-pounds with a crow's foot.
Recheck valve clearance after tightening jam nut.
Install rocker arm cover with new gasket and retain with four screws.

Governor Adjustment adjustment

Tools: Pliers

Loosen governor clamp bolt.
Push spring end of governor lever clockwise to wide open throttle position.
Hold governor lever at wide open throttle and rotate governor shaft fully clockwise with pliers.
Tighten governor clamp bolt to 70 inch-pounds (8 N-m) while holding shaft and lever.
Start engine, let stabilize and warm up at no-load.
Turn adjuster nut to obtain 62 Hertz frequency reading.
Reposition governor spring in lever slot if droop is excessive or for greater stability.
Recheck frequency and readjust adjuster nut to obtain 62 Hertz at no-load.
Check AC voltage reading; adjust voltage regulator if incorrect.

Set Ignition Magneto Air Gap adjustment

Tools: thickness gauge

Rotate flywheel until magnet is under the module armature laminations.
Place a 0.012-0.015 inch thickness gauge between flywheel magnet and module laminations.
Loosen mounting screws and let magnet pull magneto down against gauge.
Tighten both mounting screws.
Remove thickness gauge by rotating flywheel.
Repeat for second magneto.

Voltage Regulator Adjustment adjustment

⚠ Adjustment must be done only when unit is running at correct governed no-load speed

Run unit at no-load with frequency set to 62.5 Hz.
Slowly turn voltage adjust pot on voltage regulator until 124 VAC is measured.
If voltage is not adjustable, proceed to troubleshooting Problem 2.

Compression Test diagnostic

Tools: compression gauge

Remove both spark plugs.
Insert a compression gauge into either cylinder.
Crank engine until there is no further increase in pressure.
Record the highest reading.
Repeat for the remaining cylinder and record.

Cylinder Leak Down Test diagnostic

Tools: cylinder leak down tester, air source

Remove a spark plug and remove the valve cover.
Rotate crankshaft until piston reaches top dead center; both valves closed.
Lock flywheel at top dead center.
Attach leak down tester adapter to spark plug hole.
Connect air source of at least 90 psi and adjust regulated pressure to 80 psi.
Read cylinder pressure; 20 percent leakage is normally acceptable.
Listen for air escaping at carburetor, exhaust and crankcase breather.
Repeat on the remaining cylinder.

Starter Motor Performance Test diagnostic

Tools: clamp-on ammeter, tachometer (P/N 042223), fully charged 12-volt battery, test bracket

A fully charged 12 volt battery is required.
Connect jumper cables and clamp-on ammeter as shown.
Activate the starter motor and note ammeter and tachometer readings after 2-4 seconds stabilization.
Good starter will be within minimum rpm and maximum amps specification.
