6. The Inlet Needle Valve may be stuck in its seat. This can occur when stale
gasoline is used or when the machine is left setting for long periods of time. To
solve this problem the Metering Diaphragm Cover and the Diaphragm may have
to be removed and the Inlet Needle Valve manually broken loose. See the
section on the CARBURETOR. Use Dyna-Fog® Fuel Stabilizer or equivalent to
reduce these types of problems.
Symptom: Machine floods easily.
Check:
1. Is the Fuel Needle properly set?
2. The spark plug gap must be properly set. If gap is too close the gasoline will fill
the gap and prevent spark from occurring.
3. The Metering Lever could be set too far out.
4. Primer pump being depressed excessively.
5. Batteries may be weak.
Symptom: The engine runs weak.
Check:
1. Make sure the On-Off Control linkage is properly set. Linkage wheel should
rotate fully counterclockwise to STOP. If not, adjust linkage. See page .
2. Is there a carbon build-up? Check by looking into the engine with a flashlight.
