Dellorto SHA Vespa

Welcome. The Dellorto “SHA Vespa” is like a regular “SHA” but more compact. It has a smaller 50mm air filter flange, not 59. This style of carburetor was original on all Vespa/Piaggio mopeds 1970’s, 1980’s, 1990’s, and 2000’s. In the USA it was on 1972-86 Vespa mopeds, 1983-86 Garelli VIP-N, and mid 1990’s Kinetic TFR mopeds. 

The SHA Vespa carburetor has an improved choke release trigger, that cures the sticking trigger lever problem that the regular early SHA had. Vespa types have a sliding push rod, that moves up a ramp in the throttle slide when the throttle is raised fully. The solid rod pushes the choke lever/plate over a little stop tab. The torsion spring is then free to snap it back off. The top is relatively easy to put on, with only the throttle slide and spring to install, no choke device that gets damaged easy, not even a top gasket.
