Idling Issues - Holley Carburetor

I can pull the carb, adjust the screw, and re-install in about 5 minutes. And it let's me see exactly where the throttles are in relation to the t-slots. I have read that you can invert the stop screw so it is adjustable from the top. Or I may put in a hex set screw at some point to make it easier to adjust from the bottom with the carb on..

I did that during the tuning phase. Trouble is the arm comes down and slaps the screwdriver slot, so after the tune was in, I put it back. On the AG is is possible to adjust it from the bottom with a sawed off mini-driver, but it sure is a PITA.
