Thread: Carb idles high until I crack the throttle & flip the butterfly.

  1. #1

    Default Carb idles high until I crack the throttle & flip the butterfly.

    I have recently installed a Street Avenger 570 with an electric choke. Car starts right up and will not idle down until I crack the throttle and flip the butterfly. Can anyone help with this?
    Thanks, Greg

    Danny, I would be ok with just cracking the throttle, but I have to also flip the butterfly open just after cracking the throttle in order for the idle to go down.
    Thanks, Greg

    In that case, there's something wrong with the choke linkage/parts.
    See if something in this video gives you a clue as to what's wrong:
