White smoke and gas in the crank case

[opie]

My club car has run fine with no trouble until last week. There was white smoke coming from the exhaust and would not run without intermittently choking. To make a long story short I have read the posts on here and come to the conclusion there was gas running into the oil and burning out the exhaust, I drained the oil yesterday and it poured out, it was full of gas. I have read that it could be float in the carburetor or a to check the pulse line because the fuel pump has issues. Where to start? I also am not sure what the pulse line is or what I am checking it for. Any help here would be greatly appreciated.
