Carter BBD 2-Barrel: Description

The model BBD carburetor is a 2-barrel downdraft type, incorporating 3 basic fuel metering systems. The idle system provides mixture for idle and low speed operation. The accelerator pump system provides additional fuel for acceleration. The main metering system provides a more economical mixture for normal driving.

The carburetor is also equipped with a fuel inlet system which supplies a constant amount of fuel to provide sufficient fuel to the metering circuits for all engine operating conditions. The choke system (electrically assisted on Chrysler Corp. vehicles) provides temporary enrichment of the air/fuel mixture to aid in starting and running a cold engine.
