Motorcraft carburettors were used in engines manufactured by Ford from 1972 to the late 1980s. Prior to 1972, Motorcraft carburettors were manufactured under the Autolite brand name.


An automobile carburettor is responsible for regulating the mixture of air and gasoline used to create a combustible mixture in an engine. Motorcraft carburettors were manufactured in three basic types, which were single barrel, two barrel and four barrel.


Identification tags were not stamped onto Motorcraft or Autolite carburettors prior to 1965 model year Ford engines. In 1967, Ford carburettors began to meet new emissions standards with the introduction of the 4300 carburettor; vehicles manufactured after 1974 were equipped with the Motorcraft 4350 carburettor.


Identifying a Motorcraft or Autolite carburettor can be done by identifying the throttle bore size. Each carburettor has the bore size cast into the carburettor as a diameter size measured in inches.
