    2 barrel Holley carb problems

     



    I have a 430 MEL engine with a 2 barrel inlet and a 2300 2 barrel Holley on top. The engine starts fine and ticks over with no problem and also pumps ok under acceleration but will not run under cruise conditions it is searching and hunting and just a horrible drive, I have cleaned the float chamber and set the float up I have taken the metering block off and cleaned that and blown through the passage ways but has not made any difference, even tried putting the metering block on from a parts only 4 barrel I have, before I go and get a new carb I was wondering if anyone has any idea’s what else to try.
    Cheers

    Your "hunting" is lean surge. Jet it richer.

    Has it always done this or did it just start doing it?
    What if the "Hokey Pokey" is what it's really all about?

    Do you have the black solid nitrocellulouse floats?

    They tend to sink over time and the engine floods when running due to the overly high float level.

    Most parts houses carry replacements or can get them.

    It just started to do it so didn't think it was a jet problem.

    Yes the flote is the black one,
    I have now sorted it out after a day of working on it, For no reason I decided to change the points and condenser and it now starts, ticks over, accelerates and cruises.
    Thanks for the help guys
    Cheers

    No mention of timing, or if you had a point system. If the points were that far off, it should have been dieing also when you were trying to idle. Unless, you had them way to wide to start with.
    I put all the details I thought where necessary as it would start, tick over and also accelerate with no problems just would not sit at a cruise throttle position.
    The points where set correctly before I swapped them?
    But it is working now so the points/condenser must have been starting to break down?
