Mine does have that screw..I thought it was only for the fast idle adjustment only? So its also for the regular idle? WTH..makes sense but what has me confused is i have another 9077s on the car now, same carb, only difference is it does also have the idle screw.. so i may be confusing the quadrajet with this because they do have a separate fast idle screw adjustment from the rgular idle screw..but any idea why 2 identical carbs but 1 has the separate screw and one does not? Just trying to learn, thats why im asking. I appreciate the help!
