Friday night I went out and bought a 2003 Quadsport 400. Today I took it out and road for about 30 minutes and it killled when I gave it some gas. It starts up just fine and idles great, as soon as you give it gas it dies. I tried switching to reserve on the fuel petcock with no help. Any help or suggestions would be appreciated. Thanks

 

was it only after the quad warmed up that it started acting this way?

 

Yes I was after it warmed up. I tried it again this morning when it was cold and it is still doing the same thing. It sat for about 6 months before I bought it although he said he did have stabil in it. I am beginning to think maybe I sucked up some trash up from the tank? Back in the motorcross 2 wheel days I would have said the float had a hole in it. But there is no fuel coming out the overflow like a bad float would. Actually im not even sure where the overflow is.

 

I have heard that if you leave a 4-stroke quad sitting for too long, the jetting needles can get clogged with old gas...

 

Thanks I will give it a try. I talked to the guy today and he said he had the dealer put a carb kit and a fuel valve in it about 2 months ago. I also bought a new plug to throw in it in case it is fouling.

 

nice

 

Well whoever put the carb kit in it used silicone on the float bowl gasket and there was a huge chunk of silicone stuck in the main jet.
