I was riding my fourtrax 300 2x4 pretty hard this past weekend. It started cutting out on me. I checked the spark plug and the air filter but they both were ok. It would idle fine but when you get to half throttle it would start missing real bad. I brought it home and then started it on Monday and it ran fine. I do not want this to happen again. Any ideas what could be wrong? Any help would be appreciated.

 

the needle and flot could have stuck in the carb therefor flodding the engine

 

I would guess something in your gas (a little dirt or sand) clogged up your carburator, but then later passed through. If it is a 300, it is probably an old bike, with quite a few years on it, right? I would take the gas tank off the bike and rinse it out, then install an in line fuel filter.
