When working on the carburettor your existing paper seals can easily become damaged. The carburettor becomes leaky, drips and draws in undesired air. For this reason it is a good idea to use new gaskets in the case of reassembly. We stock the gaskets for the carburettor/carburettor casing and carburettor casing / engine for the SI 20.15-26-26 that are available both with and without holes for separate oil injection.

Conclusion: A must for all work on your carburettor.

While almost all Vespa engine parts have been improved and updated over the years, the gaskets have regrettably been forgotten. To eliminate this deficit, we have had the SIP PREMIUM gasket sets produced by an experienced Italian gasket manufacturer, replacing all previously paper made gaskets with items made of a tough Aramid fibre. This material is an asbestos-free mixture of cellulose and synthetic fibres and provides extremely effective sealing properties.
