Good point! I had to fix that problem on a buddies car last year. I
managed to push the stuck tip of the idle screw out of the hole with a
paper clip, needle nose pliers, and a LOT of patience. You have to be
very careful to try not to score the carb throat around the
circumference of the hole. I didn't do it perfectly but the car could
be tuned and ran fine afterward. Unscrew the idle mix adjust screws
completely from the carbs and look for them to have a tapered end that
comes to a point. If they don't come to a point, you'll never get it to
run right without getting those holes cleared.
