The air screw just unscrews straight from the bottom of the carbs towards the front. No removal of carbs required. I'm just saying if I have to make a tool to just to get them off I will, but I don't wanna rely on a brake line everytime I adjust. So make the tool, drop out the screws, cut the slot, and insert with a common flat screwdriver. Who knows, the freak kit or air pods may be in the near future, and anything else I change will require some adjustment.
