gas in airbox?????WTF

[slidinsidewayz240]

i went riding around my house a few weeks ago on my warrior, it wasn't running that great so i turned around and came back, when i did i got off to see if i could see any obvious problems and i noticed gas was coming out of my airbox, so i cut the gas off (i didn't feel like screwing with it that day) and it sat there for a couple of days. i rolled it out and it starts fine but when you give it throttle is chokes out and almost dies, WTF is the problem?? i don't know much about carbs like everyone else on this site......its completely stock and I'm pretty sure the carb has never been cleaned. please help i want to go riding again.

Sounds to me like you have multiple problems. The only way I can think of fuel getting into the airbox would obviously be through the carb. For that to happen you would have to have a stuck float and a blocked vent/drain line.

Pull the bottom hose off the carb bowl and see if fuel starts flowing out of it. If fuel flows, you found your first problem. There is probably mud stuck in the end of the line blocking it, i've also seen screws jammed in the end of the line by previous owners that didn't know why fuel was dripping out of the line and thought blocking it was a quick fix.

The next step will be to take the carb off the quad, take the bowl off the carb, and figure out what is causing it to stick. A few things to look for is indications that the floats were rubbing against the side of the bowl and possibly getting hung up on it. Make sure that the floats aren't damage or saturated with fuel. Look for excessive dirt and debris in the bottom of the bowl and clean out anything you find. Take the float needle out (attached at the pivot of the floats by a thin wire) and look for any excessive wear on the needle and seat, and any debris there.

If you don't see anything wrong (excessive dirt or indications of damage) I would replace the needle and seat and put it all back together and see what happens.
