    Default 602 Crate high RPM miss (running rich?)

    I've hade a high RPM miss for the last few races and I've changed everything in the fuel system (carb, fuel pump, etc.). Even when idling for a while, you can smell gas fumes and the plugs turn black.

    Any ideas? Running stock HEI that came with the engine - I bought it new, no issues until now.

    Might change distributer this week since I have a spare. Any other suggestions???

    Thansk in advance, KB/UD

    if it sounds like it's on a chip at 6000 but there is no chip ---the high speed air bleeds are too small
    If you are trying to run it over 6200 you might need valve springs

    you can call me tomorrow and we can discuss it
