Problem Possible Causes Probable Solutions
Engine runs, but
Bit is not rotating
1. Throttle not properly used.
2. Throttle cable not properly adjusted.
3. Bit stuck in rocks, roots, etc.
1. Make sure to fully squeeze the Throttle.
2. Have a qualified service technician
adjust Throttle cable.
3. Remove Bit from hole and clear
hole of obstructions.
Engine misfires 1. Spark plug cap loose.
2. Incorrect spark plug gap or damaged spark plug.
3. Defective spark plug cap.
4. Old or low quality gasoline/oil mixture.
5. Incorrect compression.
1. Check cap and wire connections.
2. Re-gap or replace spark plug.
3. Replace spark plug cap.
4. Use only fresh 87+ octane stabilizer-treated
unleaded gasoline/oil mixture.
Do not use gasoline with more than
10% ethanol (E15, E20, E85, etc.).
5. Diagnose and repair compression.
(Use Engine will not start:
COMPRESSION RELATED section.)
Engine stops suddenly 1. Fuel tank empty or full of impure or low quality
gasoline/oil mixture.
2. Defective fuel tank cap creating vacuum,
preventing proper fuel flow.
3. Faulty magneto.
4. Disconnected or improperly
connected spark plug cap.
1. Fill fuel tank with fresh 87+ octane stabilizer-
treated unleaded gasoline/oil mixture.
Do not use gasoline with more than
10% ethanol (E15, E20, E85, etc.).
2. Test/replace fuel tank cap.
3. Have qualified technician service magneto.
4. Secure spark plug cap.
Engine stops when
under heavy load
1. Dirty air filter
2. Engine running cold.
1. Clean element.
2. Allow engine to warm up prior to operating Auger.
Engine knocks 1. Old or low quality gasoline/oil mixture.
2. Engine overloaded.
3. Incorrect spark timing, deposit buildup,
worn engine, or other mechanical problems.
1. Fill fuel tank with fresh 87+ octane stabilizer-
treated unleaded gasoline/oil mixture.
Do not use gasoline with more than
10% ethanol (E15, E20, E85, etc.).
2. Do not exceed Auger’s load rating.
3. Have qualified technician diagnose
and service engine.
Engine backfires 1. Impure or low quality gasoline/oil mixture.
2. Engine too cold.
3. Intake valve stuck or overheated engine.
4. Incorrect timing.
1. Fill fuel tank with fresh 87+ octane stabilizer-
treated unleaded gasoline/oil mixture.
Do not use gasoline with more than
10% ethanol (E15, E20, E85, etc.).
2. Use cold weather fuel additives
to prevent backfiring.
3. Have qualified technician diagnose
and service engine.
4. Check engine timing.
After sudden impact,
engine will run, but
Auger will not operate
Shaft key or other shear pin broken by impact
to disconnect engine and limit damage.
Have qualified technician check and replace
broken shaft key or other shear pins.
Follow all safety precautions whenever diagnosing or servicing the Auger or engine.
