I have a problem and am stumped, I put a 440cc DuroMax into my cart (Hyundai) it went quite smooth I was surprised until I started the engine then things went South. While it was running it puked out a pint of oil from the pulse pump and that was caused by a droop in the vacuum line which I have corrected by raising the pump which lets any oil drain back.
Next took it out on the road and it idled just fine but when you stomped on it the engine sounded like it was a hit-and-miss going bad, broke up really bad thought it might be a bad carb gasket but that was not the case.
The only thing I have done to this engine was drill a hole in the crankcase for the pulse pump what is causing this erratic break up.
