    Default Random Peak revs

    Hey all, noobie to Nitro but learning.
    I have been given a damaged revo 3.3 that I have now repaired and got running however.
    I can start and drive around then randomly when stationary it will what I can only describe as peak revs but doesn't accelerate. I freak out and pinch fuel line to kill the car in fear of blowing the engine. I have only noticed this when hot. The throttle does NOT appear to open but still peak revs.... doesn't appear to have any fuel leaks from block BUT....... Can some one please point me in the right direction..

    25% nitro Fresh fuel
    Traxxas M/L glow plug

    Possible air leak?
    The extra air causing a lean fuel/air ratio can cause high revs.

    This engine description of the 3.3 may help you track down any places for air leaks.
    Scroll down thru,
    Cheers, Tiny

    Also would have been my suggestion.
    Anything Nitro/ alcohol is pretty sensitive to that.
