Ford produced only one type of one-barrel carburettor for the 1966 model-year, the Autolite 1100. The carburettor consists of two main assemblies, the upper assembly and the lower assembly. Together, these two assemblies route a mixture of air and gasoline into the intake manifold, where the mixture is then routed to each of the engine's cylinders. As with all carburettors, the 1100 does require periodic adjustment to ensure that it operates at its most efficient. Making these adjustments is fairly straightforward, but should not be attempted without some familiarity with carburettors.
Remove the screws that secure the upper half of the carburettor to the lower half of the carburettor with a standard screwdriver.
Lift the upper half of the carburettor off the lower half of the carburettor to expose the float that hangs from the upper half.
Invert the upper half of the carburettor and pull the gasket off the carburettor.
Measure the distance between the gasket surface and the top of the float with a dial indicator. The distance must be 1 3/32 inches.
Adjust the float level, if necessary, by bending the float arm tab.
Position a new gasket onto the upper half of the carburettor, then lower the upper half onto the lower half.
Install and tighten the carburettor's retaining screws with a standard screwdriver.
Turn the dashpot's adjusting screw outward with a standard screwdriver until the screw clears the dashpot's plunger.
Turn the adjusting screw inward just until the tip of the screw contacts the plunger.
Turn the adjusting screw inward 3 1/2 turns.
Loosen the three screws that secure the choke housing to the side of the carburettor with a standard screwdriver.
Rotate the choke housing until the arrow on the housing aligns with the "1/8" mark on the side of the carburettor.
Tighten the choke housing's three screws with a standard screwdriver.
