Need help Diagnosing Yamaha G2 Gas, first smoked, now oil out of carb

[Redparrott727]

Hi, i'm a new person on this forum seeking help, i have a yamaha g2 golf cart, for about a year now it has smoked and burned oil, and now just yesterday i took it for a ride and i came back and parked, not a problem, then go to start it again and i believe it is backfiring, and it almost looks as though a mist of oil is backfiring out of the carb? any guesses to what i should check first?

It sounds like your oil ring is bad, might be time for new rings, a rebuild or a clone engine swap.

The first thing you might want to do though is change the oil and make sure there is only one quart of oil in it, sometimes the dipsticks don't read right, especially if your cart is lifted.

I did add some oil right before I left for the long ride, But i would have figured the extra oil would have caused it to act up right away as opposed to later on after it cooled off? Also would anyone happen to know where the oil drain bolt is on these? That and does anyone have access to a yamaha g2 repair manual? I appreciate the help

Pm me an email address and I'll help you out with the manuals.

Oil plug is a bolt just like a cart on bottom of pan, part of the block in this case, should be easy to locate under cart unless you have some kind of shield under the cart. Some had them.

Too much oil will puke out into the air filter and make a big mess.

I'm still not sure to figure out how to pm yet but when i figure it out i will, thanks Honorostick. Also I have an update, I drained the oil and put 1 quart in with no luck. My dad and I took the small head cover off, and what happened is the exhaust pushrod popped out of place, we put it back in place, adjusted valve clearance and it ran fine for a while, then while riding this time happened again. Any suggestions?

Check the spring see if its broken or weak or other issue. Should be able to push them down with a hammer handle or something to check motion, if you flip the rocker out of the way or remove. Don't have it at TDC if you jamb the valve way down not sure it will clear, don't know.
