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.
