Scootopia Lambretta SH2/22 Carburettor

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). Sticky's Spanner's Manual says - "Getting a carb off a manifold can be very tricky if it hasn't moved in years. You can try heating it with a rag drenched in boiling water, but DON'T heat it in any other way ; particulary with a naked flame. If you cant grip the carb in a gloved hand and twist it to get it off, then it may be tapped off from the other side of the scooter with the words "a carburettor is a sensitive instrument" ringing in your head. One way is to rest a peice of wood (gaffer taped to prevent splintering) against the back of the carb and tap it to encourage the carb to start moving. Once loose you should be able to twist and pull it off the manifold".
