let me start by saying i am sorry if this has been asked before, but i couldnt really find anything like this in the search :eek:. i installed a new out of the box edelbrock 600 cfm carb with a manual choke on a stock 305. with every other edelbrock that i had, i turned the mixture screw in until the motor started to die, then backed the screw out a turn and a half. do this for both sides and viola! its set. on this new one, i can screw both all the way in and it still idles. am i missing something. i had it idling smooth and even took it for a quick run. seems to be ok, but the screws dont do anything. :confused:

maybe the throttle stop is set open far enough that it's not drawing through the idle circuit.Advance the timing so it idles faster close the throttle stop down to get the idle back then try adjusting the mixture screws.

It sounds to me like the throttle blades are open too far. Where is the timing set? what RPM is it idling at?
