After i shut my 4 wheeler off gas pours out of it

You need to first determine whether the problem is fuel or electrical. Remove the sparkplug and pour in a small quantity of gas. Replace sparkplug and high tension lead. Crank it over. If it does start and run a bit then your problem is fuel and not electrical. If it does not fire and the sparkplug is wet, then start be replacing the sparkplug with a new one.

Carb has bad gas in it and the float needle is stuck shut thus not letting fuel into the carb

hi, sounds like a stuck float in your carb. Try tapping the carb briskly! sounds like gas is slowly dripping in the bowl overnight and you burn it the next day. I would take the bowl off and see how much gas pours out. It should come out like a light stream of pee. Could be cloged fuel filter or a gumed up or broken float, carb rebuild kits are cheap.
Good Luck!

sounds like your getting to much fuel in the bottom of the carbie should be a float which controls the amount try bending it slightly so that it shuts off quicker

the floats in the carb are stuck or adjusted to high

A common problem with Yamaha 4 wheelers is soft rubber on the intake manifolds. They will often crack or separate causing poor running. I think you are either dealing with a cracked, broken, or separated intake manifold or a cracked, broken, or missing intake o-ring on either end of the intake manifold. Take the manifold off and inspect the manifold and the o-rings.

take your carburetor apart and clean it . it sounds like your float is sticking . good luck .

che ck if their is a spark after the coil before the spark plug, if no, replace it.

yes there is a tube that goes on it. It hangs straight down about an inch or two past the botom of the 4 wheelers frame. It is for a overflow of gas, which is usally caused by either dirt in the carb holding the float to high and allowing the gas to just run straight thru and out the bottom of the carb or a bent or maladjusted float setting. But since you said it just started, i would suggest this. I have fixed many and many bikes by simply removing the carb bottom and cleaning it with carb cleaner. It onlty takes a small piece of dirt between the float needle to keep the needle from making a good seat in the carb. Clean it well Please be carefull and keep the carb well away from your face as to not get any blowback of cleaner in your eyes(IT BURNS) This should fix your probblem
