Small Engine Troubleshooting Problems? Ask a Mechanic Now.
It just loses power, it does not quit? When it loses power, run the cylinder test. Loosen the spark plug wires, and with engine idling, remove one wire at a time, if engine dies when either wire is removed, the opposite cylinder is not firing. With good spark, and with compression, have the valves been adjusted? FD501 model is set at .010 intake and exhaust.
Has it been checked when it is ho and problem is there? And you have set the valves?
Has it been ran with test line on the inlet of the fuel pump, dropped back into the fule tank filler opening, bypassing the tank and outlet.
Valves are set at .010 inch?
OK> I will opt out. Maybe someone else can help. Please do not respond to me, or it will lock the question.
