Problems when warm

ONIN2 · 08-07-2009, 01:56 PM

My friend has a mid 90's Yamaha Golf cart (4 stroke) that runs fine when cold, but after it warms up, it will not "catch" and get up and go. It tries, but just sits there and putt..putt...putt. Also, he way overfilled the crankcase when changing the oil, but that has been corrected and the air filter cleaned quite a few times.
Any help would be appreciated.
The spark plug was just looked at and it is black.
Carbueration?

Thanks,
Dave

OK 2 events, was it hard firing before the oil over fill? I would start with a plug they are cheap.
