I would suspect that the float is stuck in the down position allowing fuel to constantly flow into the bowl and then out through the overflow hose. Remove the float bowl and then remove the float and see if there is a hole in the float. Also check the needle valve and seat. The float will rise as the bowl gets full and when the float rises to the top it shuts the flow of fuel off. If there is a pin hole in the float it will fill with gas and cannot then rise as it should. The flow valve also can be stuck open allowing fuel to constantly flow. You need to inspect all these components to see why the fuel is not being shut off when the bowl gets full. It can be varnish is clogging to passages especially if you have not been using a fuel stabilizer when storing your ATV. You will need a can of spray carb cleaner to clean it out. Remove the jets and clean them out and and see if this helps. In other words clean everything of varnish and gunk. Once you remove the float bowl you will have a good idea if you have a dirty carb that needs cleaning. If you do not feel comfortable tackling this then take the carburetor off and let a professional give it a good cleaning and possibly a rebuild. It is critical that the float be set to allow the correct amount of fuel to stay in the reservoir.

2002 yamaha wolverine 350 4x4 fuel mixture screw has to be adjusted way out to run right carb is clean and if turned out 2 turns it will pop in exhust and cut off when you stop. Cant turn out enough to...


turning the screw way out makes the mixture lean, so the problem must be the carb is too rich.
check all the jets were installed correctly when the carb was cleaned
make sure the carb float bowl is not flooding.
Check the fuel tap is working correctly.
make certain the airfilter is clean.
check the engine has correct amount of clean oil( not fuel contaminated)
