fitment helpThe air mixture screw should be wound in until fully seated (do not force it) and then wound it back out to the prescribed amount. For these carbs the Lambretta workshop book suggests 0.5 turns out as a base setting, many dealers prefer 1.5 turns. From that when the scooter is warm, you can adjust the screw to fine tune. turn the screw out to richen or in to weaken. More information on this can be found in the latest Sticky Book, Page 172.
