Many times there is a stumble from the primary throttle blade open to far for the idle speed to be correct. If that makes sense.
Drilling a hole in the throttle blades was old school. Or carbs having 4 corner idle circuits and a secondary idle screw. Just a thought you may want to check if you have a larger cam that would need to have more fuel at idle. You should never be above square on the transfer slots.
