    I have a Norton 750 Commando which had the Amals replaced with the
    Sudco 34mm Mikuni.

    When I received the bike, it had an improper throttle cable which
    caused the motor to race to full throttle the first time I started
    it. (Didn't try that again).

    Replaced cable.

    Now the bike starts easily with the enricher on...first or second
    kick...idles cleanly. As soon as I attempt the pull the enricher off,
    the bike start choking and dies immediately. This is not a "motors
    too cold to take enricher off" choking, but definitely an improper or
    insufficient fuel mix choking.

    Obviously, I'm not a Mikuni expert. I'm just trying to get some ideas
    on what this might be.

    Any helpful hints? Needle adjustment possibly?
