MOTORCRAFT Model 2150 2-Barrel: Description

Motorcraft 2150 carburetors have 2 main assemblies: the air horn and main body. Air horn contains choke plate, fuel bowl vent, and hot idle compensator. Main body houses throttle plate, accelerator pump assembly, float assembly, power valve and fuel bowl. Each bore contains main and boost Venturis, main fuel discharge, and accelerator pump discharge orifices.

On some applications, booster Venturis contain variable high speed bleed control system, which allows control of air/fuel mixture for improved high speed operation and low speed responses.

Vehicles sold for high altitude use (above 4000 ft.) contain an altitude compensator. This circuit compensates for thinner air by metering an additional amount of air into the air/fuel mixture, preventing an over-rich situation. An automatic device (aneroid) reacts to atmospheric pressure and overrides the compensation feature at lower altitudes.
