"Scootopia made Lambretta GP150 & 200 22mm carb to fit all Lambretta series 1/2/3 & DL/GP (with GP150 manifold). Perfect copy of the Dellorto SH22/2 carb. GP200 jetting set up already fitted, comes with an extra GP150 slide and atomiser.
fitment help The 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.
(Did you know, Innocenti originally used a 115 main jet in early production 150 & 200cc models. In July 1969 this was changed to a 118 main jet)."
