Weber 40 IDF Carburettor

The IDF is ideal for use on most opposed-cylinder engines, or on V8 engines using independent runner designed intake manifolds. It offers relative low cost for performance gains, the IDF is hard to beat. With its central float chambers, full calibration capabilities, compact alloy body and wide variety of available sizes, the IDF Series has been and continues to be the winning choice for a synchronous, 2 barrel, downdraft carburetor.

The IDF features diaphragm type accelerator pump circuits and ball bearing throttle shafts. These carburettors have similar adjustability as the side-draught DCOE series. When used with an adapter, the IDF will replace the Solex 40 PII carburetors used on many Porsches.

This is the 40 mm size which is ideal in pairs for use on VW engines up to 1900.cc. A wide range of manifolds are available to fit these carburettors many engines.
