Fuel and exhaust systems - carburettor models / Carburettor - overhaul


1 A complete strip-down of a carburettor is unlikely to cure a fault which is not immediately obvious without introducing new problems. If persistent carburation problems are encountered, it is recommended that the advice of a VW dealer or carburettor specialist is sought. Most dealers will be able to provide carburettor re-jetting and servicing facilities and if necessary, it should be possible to purchase a reconditioned carburettor of the relevant type.

2 If it is decided to go ahead and service a carburettor, check the cost and availability of spare parts before commencement. Obtain a carburettor repair kit, which will contain the necessary gaskets, diaphragms and other renewable items.

3 When working on carburettors, scrupulous cleanliness must be observed and care must be taken not to introduce any foreign matter into components. Carburettors are delicate instruments and care should be taken not to disturb any components unnecessarily.

4 Referring to the relevant exploded view of the carburettor (see illustrations), remove each component part whilst making a note of its fitted position. Make alignment marks on linkages, etc.
