OT- Golf cart trouble

Royse · Jul 14, 2013

I think John T started this.

I hope he doesn't find the same things I did!
Mine quit while driving across the yard.
First picture was the first sign.
I thought pistons were supposed to be round.
Guess carts aren't supposed to last more than 40 years. LOL
This is a 1973 Harley Davidson 4 wheeled cart.
Yes, it had the correct 2 cycle oil mix in it.
Hopefully I'll have it up and going in a week or so.

Even with the correct gas/oil ratio, if it starts running lean, the piston will get too hot and gall like that. I would suspect a lean fuel/air mixture.

Thanks for the tip Hay_Man, I think that may be the case as well.
This is an old Tillotson carb with the built in diaphragm fuel pump.
The rubber gets dry and weak, specially with ethanol gas.
Got a rebuild kit on the way for the carb too.

Yep, I have experience with a 2 stroke air cooled engine that would gall and sieze. Turned out to be case gaskets leaking and allowing an air leak into the engine, resulting in too lean a mixture...

Can you bore the cylinder or is it one of the infamous chrome
plated aluminum jugs ?

Royse · Jul 14, 2013

It could be honed, (tapered bore) but the price of a piston, rings,
gaskets etc separately come to almost as much as a "kit".
Kit contains the jug plus all the above for just under $150.
Sure can't replace the cart for that kind of money.

Be sure to check the crankshaft seals. A leaking seal will cause it to run lean. Lean condition will cause a meltdown.
