I posted on another persons thread but they were having the smoke but not running problem. This 96 Club Car golf cart starts and runs fine but after a minute it blows smoke out and gets worse the longer it runs. Checked compression, 150 #, set valve clearances, cleaned carb, replaced breather reed valve,. This cart had the carb float sticking, filling crankcase with gas, drained and refilled crankcase 3 times plus oil filter but to no avail. Gas is good. Thinking along the lines of a bad oil ring or faulty oil pressure relief valve. Before I yank this mill, anyone got any tests I can run to confirm suspicions. It was running fine, no smoke before the carb float sticking but don't know for how long, I'm at a golf course with 69 other carts. I fire this cart up, valve cover off and nice spurt of oil from breather, drain holes all open and no excessive amount of oil in valve chamber so it's not over filling and running thru carb. Help needed, guys.
Club Car Blows Smoke But Runs Fine...

Any oil on the spark plugs or in the muffler also make sure that the crankcase vent hose from the crankcase to air cleaner is not plugged,crimped or broken if you ran the engine very long with fuel in the oil it is possible that you may have problems with seals or rings. Check out these other things and follow up with us.
I've ran this cart several times and plug comes out perfect, no oil deposits. Crankcase vent is not plugged, pushes no oil to carb. With the good compression reading sort of ruling out rings and valves and wondering about oil pressure relief valve, going to have to jerk the engine one way or the other but rather nail down the problem while it's in the cart and I can run it. No much I haven't done or tried. Puzzler being that it takes a minute of running before the smokes starts and continues to get worse, why I'm leaning on the relief valve, building up pressure and not relieving back to crankcase and forcing oil past the piston. Thanks for your input.
Finally got around to jerking the engine. Installed new rings, check cylinder bore, within specs. Replaced pressure relief valve seat, spring and ball while I had it out. Replaced the breather reed also and installed it back in the cart. Fired it up and as before, runs for 3 minutes clean, then the smoke starts and gets worse the longer it runs. Any other ideas?? Adjusted the valve, everything looks good when I had it apart, somehow oil is getting into the combustion chamber causing the smoke, after running awhile, plug comes out clean, no oil deposits, normal color.

It sounds like the muffler has oil in it. Probably from when the float was sticking. The crank case got over full and it pumped oil/gas into the muffler. Is the cart burning oil? If it's staying full of oil I'd run it hard on a long run to burn the oil out of the muffler...
During the first run thru before rebuilding the engine, I thought of the muffler being coated with gas and oil and swapped it out with another muffler, same deal, smoke continued. Kind of rules out oil in the muffler. I mean its identical to before the ring job, runs clean for a few minutes and then the smoke starts and just gets worse. Let it sit, fire it back up, runs clean and then the smoke starts again, always takes a few minutes for the smoke to start, oil getting in the cylinder but how? After I installed the rings, oiled up the cylinder, piston hard to go up and down, nice tight fit, orientated rings acording to manual, checked bore with new ring, within specks but didn't have an inside mic to see if bore is out of round. Cart was running fine before float sticking and filling crankcase with gas, also loaded cylinder with gas and wouldn't turn over until removing the spark plug and pushing gas out. After draining crankcase and refilling and draining again, new filter and carb cleaning, the smoke started. As I stated before, I don't know how long the cart was run with the gas problem before it was tagged in need of repair. We're a publix golf course and I got 69 other babies to care for. Sitting here waiting for some remedy to pop up.
Did you possibly perform a compression check after it started smoking? This was on one of my four wheelers but it did the same thing. There was a crack in the cylinder opened when hot. When I did the compression check after warm up (smoking) It dropped rapidly. Worth a shot Good luck

Wondered what ever fixed your smoke problem, I have the same thing with my Yamaha?

My Yamaha had the same problem. After fixing the carburetor and draining the old oil / gas and filling with new oil, it smoked a lot. Here on the island I live on, golf carts are legal on the street
(if registered and insured), so I tried driving it around to clear the problem. But it was embarrassing, to say the least.
I noticed that the smoking seemed to be diminishing with each use so I started getting up early to drive it around before anyone was up. It was definitely easing so I continued to drive it incognito
and soon enough the smoking abated and it has run perfectly ever since. It gets tons of use and consumes no oil. I'm not sure why all this occurred, but I'm not arguing with success.
Hope this helps.

I'v got a 96DS doing the same thing. It had carb issues 5 months ago. crank case had gas in it. I changed the oil and filter and, cleaned the float bowl. On the third test lap around the house it started smoking. I parked it 5 months ago and this week changed oil and filter. replaced the carb, drained and cleaned the fuel tank, replaced all fuel hoses and filters. Once again on the third lap SMOKE. WYG?

I have the same problem 2009 EZGO....I do not drive it regularly and noticed tons of smoke when driving. I changed the oil and found gas in oil but motor good, runs great.... Very low hours on cart so I am pretty sure motor fine. After changing oil same problem....After reading and talking to local cart guy...I installed shut off valve on fuel line...When I park I turn shutoff valve if I know I am parking for a while I shut valve off and run all gas out of it...probably may not be the best way to fix but works for me...
