Carburetor gasket set BGM ORIGINAL Dellorto SI20/15, SI20/17, SI20/20, SI24/24, SI26/26

Gasket set for the classic SI carburetor series from Dell’Orto. These were used on all Vespa engines in the Largeframe series. The term Largeframe includes all Vespa models manufactured from around 1957 (with the introduction of the Vespa VNB models) with rotary-valve intake (a crankshaft cheek controls the mixture inlet into the crankcase). This includes all VBA, VBB, VNB, VBC (Super), GT, GTR, GL, TS, Sprint, Rally and PX model series.

The gasket set is available as:

• BGM1212CA1 small set (without float needle)

• BGM1212CA2 large set (with float needle)

The gasket set includes all rubber and fiber gaskets, but not the paper gasket for the float chamber. This can almost always be reused if in good condition.
In addition, it is often included in engine gasket sets, so many mechanics already have an ample supply of these seals.
