I have a 2000 warrior and haven't run it in approx. 5 weeks. Today I went to start it up and as soon as I turn the gas on, gas goes pouring out of the overflow tubes on the carb. I tried heating up the carbs with a blowdryer, but still had no luck.

I am able to start the quad when the gas is off (apparently just enough gas gets through the line to allow it to idle), but as soon as I turn the gas on, the engine sputters then dies, and gas goes pouring out of the carb.

Does anyone know what the problem may be and how to fix it!?

Thanks

 

A post in the yamaha forum may help.

 

sounds like your float is stuck

 

it does sound like your froat is stuck, tap on the bowl with handle of a screw driver and see if it quits dumping fuel

 

Either your float needs adjusting, or the needle valve has a bit of grit underneath it holding it open. What I do, is go out and land a few huge jumps, and usually that will get a stuck needle freed up....

 

I would think the float is most likely to be the problem.
