Yes, turn the screw out 2 turns and see where it idles, adjust from there. They all seem to be different. The idle screw just moves the slide up when screwed in, so there is no magic number of turns.I turned the screw too many times and dont know how to get it back to stock. Many carbs turn in all the way and then out a certain amount of times. Does anyone know?
