    Help me out carb experts!

    I'm having troubles with my quad running. I have a hmf slip, k@n filter and I'm running the air box lid. I have a a 160 main jet and 42 pilot, and everything is stock. When I'm at complete idle and pop the gas it bogs before it revs. Any help??

    mine does the same thing did you take the carb apart and clean it ? if not try that and see if it helps then check your spark plug and make sure it isnt running lean or rich

    carbs clean as a whistle. I'm under the impression it's lean, but plus looks fine

    maybe the jets gloged does it leak gas if it does the float might be stuck open and if your plug has white on it it is running lean

    well I've just recentely cleaned the carb to a shine, no gas leaks, clogs, or stuck floats. I just need a carb expert to access the problem w/ my jetting.
