Carburettors (all types) - dismantling and reassembly
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 Ford dealer or specialist is sought. Most dealers will be able to provide carburettor re-jetting and servicing facilities and if necessary, it should be possible to buy 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.

remove each component part whilst making a note of its fitted position. Make alignment marks on linkages etc.
5 Reassemble the carburettor in the reverse order to dismantling, using new gaskets, Orings etc. Be careful not to kink any diaphragms.
