Club Car Gas Golf Cart Backfiring and Won't Start

If the engine only has 30# of compression your probably looking at a rebuild. 140 to 160 pounds of compression is what you need. A little lower would be ok but 30 you've got some real problems. Just wondering have you worked on the starter/generator at all this might seem like it doesn't apply to your problem just thinking out loud.

I agree with ftfixer. If the valves are set right and you only have 30 lbs of compression there's something wrong internally either rings or the valves have carbon on the stems and aren't seating. It possible the rings are washed down with gas. Try shooting some oil in the cylinder and crank it over a few times then do the compression test again.

Are you sure the service manual says 57psi? It should be 140+. I've seen the valves carbon up on the Club Cars and hold the valves open a little and cause them to loose compression. Sometimes you can tell by looking at the valve springs and you might notice one isn't as tall as the other.
I could be wrong, but on page 2-4 service data(under compression) it says minimum
4kg/cm2, 57psi with electric start.
I'm not being a smart...... this is the first service manual on an engine that I have ever read and there is a good chance that im reading it wrong..
Not only will I not be offended, but if I'm reading it wrong please correct me, and tell me where I'm messing up reading this thing. I have to learn, because I cant afford to have someone fix the cart.

Sounds like something got in there and bounced around for awhile. Got any pics?
I can post some pics after I pull the head again.
I took the valves out and hit them with some valve compound (not the hardest project with two people and a couple screwdrivers) but it was hard to find a drill with a small enough chuck. I put it all back together and still no luck, but now after jostling the carburetor around the engine is flooding also, gas just pooring out. Now my next step is to retest for compression (if still bad ,looking into rings)

I'd pull the engine to do the work. Keep us updated on how it goes...

Do you have a Club Car clutch puller tool? I think you'll need it to get the clutch off. I've heard of guys using a 2x4 between the clutch and the motor case. I always use the puller.
