Information on product safety

Replacement carburettor for the no longer available original SI 20/17 from Dell'Orto.

Produced by Spaco (India) under licence and quality control from Dell'Orto.

The carburettor has an integrated choke mechanism which is controlled by a cable. Some old vehicles, such as the VNA1 and VNA2, have an external choke control (lever directly under the swing saddle). In this case the carburetor sump of the PX80-150 models (or also e.g. Sprint150) would be needed additionally as well as an air filter of the Vespa PX models.
