Once you have corrected the distributor remove the carb and flip it over.
look at the throttle plates and idle fuel transfer slots. reset both the primary and sec throttle idle stops
so the transfer slot exposure at idle is correct .020" .030" ish and even.

If the throttles are too far open and or too uneven at idle it will idle like crap.
The extra idle base timing 20-24deg allows correct trahsfer slot exposure at idle
with that cam. The Performer RPM manifold is a much better intake for that motor and that cam.
