Carburetor - MOTORCRAFT 2150 2-Bbl: Description
The Motorcraft 2150 carburetor has 2 main assemblies: the air horn and main body. The air horn contains choke plate, fuel bowl vent, hot idle compensator, and a cranking jet. The main body houses throttle plate, accelerator pump assembly, float assembly, power valve, and fuel bowl.
Each bore contains main and boost venturi, main fuel discharge, accelerator pump discharge, idle fuel discharge and throttle plate.
On some applications, booster venturi contain variable high speed bleed control system. This system allows control of air/fuel mixture for improved high speed operation and low speed responses.
Some high altitude carburetors, above 4000 ft. (1219 m), use an altitude compensator to control air/fuel mixture. This circuit compensates for thinner air by metering an additional amount of air into the air/fuel mixture, preventing an over-rich situation. An aneroid (automatic device) reacts to atmospheric pressure and overrides the compensation feature at lower altitudes.
