The Carter AFB 1-barrel carburetor was originally designed for use on the six-cylinder engines found in Studebaker vehicles from 1959 to 1962. This particular carburetor model, the AFB, is known for its advanced design and excellent performance. The Carter AFB utilizes a single barrel with a unique air horn design, which helps to improve engine idling, acceleration, and overall fuel efficiency.

The Carter AFB carburetor is characterized by its rounded, cylindrical shape with a flat top. It has a gross size of approximately 2.2 inches in height and 4 inches in overall diameter. The carburetor features a perfectly calibrated pilot circuit, which ensures stable idling and easy starting, even in cold weather conditions. For optimal power delivery, the main circuit of the AFB is equipped with a regular-bore, full-radius, tapered venturi.

These nozzles ensure proper fuel delivery, which is crucial for a smooth and powerful engine performance. Additionally, the airbleed mechanism integrated into the Carter AFB helps to eliminate surges and vibrations.

The choke system of the AFB carburetor is designed to ensure efficient cold starting. When engaged, it fully blocks off the fuel passage, allowing a richer fuel mixture to be provided, which aids in a quick and easy start. The choke can be operated using a lever located on the side of the carburetor or through the use of a vacuum-operated system.

Other notable features of the Carter AFB 1-barrel carburetor include its fuel path design, which incorporates a primary and secondary float bowl with a displacement capacity of about 1.3 quarts, and a secondary jet which aids in providing a fuel-rich mixture during acceleration. To maintain proper ventilation and combustion, the carburetor is also equipped with an air cleaner mounting plate, which ensures a good airflow into the engine.

Proper adjustments and calibration of this carburetor are crucial for optimal performance and reliable operation. Proper tuning can be achieved by following the manufacturer's instructions, or enlisting the help of a professional mechanic.
