Thread: Carb bore rebuild? slight leak.

    Default Carb bore rebuild? slight leak.

    Shineing a light into my carb I can see an opening along the top of the throttle disk. I figure this will affect idle. Will it? Can I tune around to compensate? It's very slight.

    Options avail to fix this?

    Often most of the daylight can be closed by installing a fresh throttleplate. You can judge your plates wear by the "key' formed by the protecting shaft: (see attachment)
    If the corresponding 'eyebrow' of wear into the carb bore approaches the idle bleed holes, then tuning becomes difficult for idle and very low speeds.

    The normal repair for a worn bore is to hone it for an oversized plate and venturi kit.
