Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Welcome to JUST ANSWER small engines, let me try to help you !! You say engine runs fine? Are you sure the engine is starting? Or is it just running on the starter/generator? If engine does not start, you get no engine speed to engage the centrifugal clutch. Are you getting spark to the spark plug? Is the carburetor getting fuel from the fuel pump? If the engine is starting and will not pickup rpm, is the throttle cable moving the throttle plate in the carburetor?
It is the coil, and it has to supply the spark for the plug! If it is loosing spark engine quits,
I assume this is four cycle engine.?? Not two cycle that has to mix oil and gas.
