FH381V AS29-R. The machine doesn't want to start after sitting over nite. If I put a small squik of quick start away it goes. And it will start on almost the first pull the rest of day. New plugs, new gas filter, valves set, carb overhaul last year. As an experiment I shut off the gas from the tank and let the machine run until it died. The fuel filter was on the pump side of the cut off and it was not sucked dry when engine stopped Then I opened up the fuel cutoff and the machine wouldn't start until I hit it with quick start. I am leaning heavy to fuel pump, am I correct? Unit is going into fourth year. Both spark plug coil replaced last year.
