It's possible, but it will be difficult. That engine is pretty large, not sure it will fit in the cart without modifications.

Also, you need to consider what are you using from clutches. If that engine came out of a generator it probably has a tapered crankshaft, no good. You need to use an engine with a straight crankshaft, preferably 1". If it has a 1 1/8" crankshaft, you will be limited with your drive clutch options.

Look at your current engine, which way does the engine spin? If it spins clockwise you would not want to use that other engine, it spins counter clockwise. You will have to use reverse as your forward gear, and it's ratio is really low, so your speed will be slow. If the original engine spins counter clockwise, then most aftermarket engines will rotate the correct way.

You will need a lift kit or a dropped engine cradle to fit that engine, so fabrication might be in your future.

It's not an easy project. If you have good mechanical skills you could do it, but again, it sounds like some fabrication will be needed.

If you don't have good mechanical skills, you'll need lots of help.
