Default Carburetor problems

Hey guys, I have a 1990 yamaha 350 warrior and its got some carb problems. Right now it leaks fuel through the over flow when not running (Pretty sure that is the floats problem) it only runs with full choke on and it kinda makes a popping sound but its not a back fire, just sounds like a bunch of vapor coming out the exhaust. all this happend after i put some new gas in it, maybe the fuel was bad and carb cleaner might work?

Could be some bad gas. Have you ever had this problem before. As for the gas coming out of the bowl thats because of your float isn't set right allowing gas to seep out around the needle.

yep a carb clean fixed 100% bad gas. the guy actually had to drill the crap out from the jet, pretty bad.
