This gasket set is explicitly designed to seal and service the classic Weber IDF series downdraft carburetors, specifically the highly popular 40 IDF and 44 IDF models. Whenever a carburetor has been disassembled for cleaning, tuning, or general inspection, it is extremely crucial to replace the old paper and rubber gaskets. Old gaskets dry out, shrink, and completely lose their natural sealing ability over time, which inevitably leads to hazardous fuel leaks and unwanted vacuum leaks.

The kit contains all the fundamental gaskets required to restore the carburetor's external and internal seal, including the vital top cover (float bowl) gasket. Please note that this is strictly a gasket set; if you also need to replace internal mechanical wear items such as the needle valve and the accelerator pump diaphragm, we highly recommend purchasing one of our complete service kits instead.

Compatibility:

• Weber 40 IDF
• Weber 44 IDF

Workshop tip: Always clean all mating surfaces thoroughly using a delicate gasket scraper and brake cleaner before installing the new gaskets. Never use liquid silicone gasket maker anywhere inside or around the carburetor, as excess sealant can easily detach and permanently clog the highly delicate internal fuel and air jets.
