    Default how to set the fast idle cam on electric choke

    Hello,

    I'm having quite a hard time to set my electric choke on my holley 750 Vacuum secondary , the voltage is correct but seems the fast idle cam is not doing the job , I set the choke cap right in the middle so how many turns is the factory set up for the fast idle screw? And is there a procedure as per how to set the fast idle cam??

    Thank you!

    The procedure is similar as to the factory service manual.
    It involves adjusting the fast idle screw to achieve a certain idle RPM (usually around 1600), while on the highest step of the fast idle cam.
