    carb adjustment

    what is the best RPM to set the idle at on a 259 V8 with a 2b Stromberg carb. The manual says 550 - 600 rpm and I was just wondering if setting at 650 or 700 rpm would be better or worse. thanks

    If the car is an automatic, a high idle will cause more creep when in gear.
    Try increasing the idle speed and see if you like it. If not, adjust it back.

    Chock the wheels and set e brake. Adjust with car in drive. Otherwise its just like thunderations said: if you don't like all you gotta do is turn the screwdriver just a little.

    If you get too crazy with the Higher than normal Idle, it will cause a late downshift to 2nd. Gear, and depending on the Ignition Timing setting and Temp., it could Diesel (run on) at shutdown.
