Re: Honda gx620 on golf cart occasionally bogs down &...
What ussually causes white smoke to come out the exhaust is oil being sucked up in carb. Typical causes are too much oil in crank case or PVC valve. Or really bad piston rings

www.golfcarthotrod.com > Golf Cart Repair Apr 30, 2010 - Electric E-Z-Go Golf Carts are becoming more popular every day ..... I have a ezgo carryall gas golfcart. it has began to pour smoke from rear.
It could be doing its job, sounds like what you put in tank is problem. Oil change would not cause that. I would not worry unless it keeps going after fuels runs down.
Sounds more like the engine has been tipped, oil can then enter the air filter box via the engine crankcase breather, allow the engine to run with the filter removed until the smoke clears, refit a new filter if it is a paper element type and try again.
You either need to add the specific oil made just for that Golf cart, or you have excessive amounts of water in the gas tank. A solution to that would be to take a tube and syphon the gas out of the tank. One last problem could be that you have sludge buildup from years of little dirt sediments in the gas that are blocking the needed gas from going through the tube and into the engine. Hope I helped.
I would talk to who cleaned the injectors, I don't know if it something they did or not. It could be a stuck open injector. The exhaust would have a raw fuel odor if it was. What it sounds like is a blown headgasket, which can just happen. The exhaust would have a sweet smell to it. Usually starts as a small leak (between cyl. 2 & 3), the engine burns the coolant while driving which you don't see. Then the coolant level gradually drops to a point where the car overheats, which warps the head, causing a large leak. Now you see the coolant burning (white smoke).
Good luck Honda Al
