Yamaha G5A

my dad's Yamaha G5A run's, but doesn't go. It creeps or not at all. I noticed that the drive belt slip some or does not move. The belt looks good. Any Ideas?

Just a thought, normaly when some one say's runs (means the starter/generator) is turning over the engine. Then you could have, engine turns over, won't fire up. I woild suggest simple things first, when you push on the accelerator, does the govenor shaft or throttle shaft move? If not, a bloken accerator cable #1 or #2. You need compression, you need fuel and you need spark. If the engine "runs" and goes thru "rpms" as you push the accelerator pedal, then its time to look at clutch problems. Good Luck Dave Let us know what you find.

First off, I was wrong It's a yamaha G3A. And its the motor. It's getting no gas. I need to find the fuel pump location. But that's for another night.

I bought what I believe is a 93 Yamaha G5A Sun Classic. Rod was a knockin. Tore into it. Yep, that's it....ran it without oil. Most suppliers and forums skip right past the G5A without mention. Near as I can tell, it has the J38 engine in it. Right? - Wrong?. I got dial calipers and telescoping gauges to do an initial assessment of damage but have no reference material to compare my readings with specs. If this engine is too far gone, I'll stuff a 13 HP Predator engine in it and call it a day! Rebuilt quite of few small engines, just not too seasoned on Golf Carts at this point.....Any an all help would be greatly appreciated. Thanks in advance
