The Carter AFB 2589S WCFB 4-barrel carburetor is a vintage automotive component that was originally designed for use in the 1957 Mopar Chrysler Desoto 354 V-8 engine. This carburetor is a testament to the engineering prowess of the mid-20th century automotive industry.
The 2589S WCFB carburetor is a four-barrel model, which means it has four separate intake runners linked to a common throttle plate.

The carburetor features a unique two-piece cast aluminum body, which is both durable and lightweight.

The carburetor is also equipped with a manual choke, which allows the driver to control the air-fuel mixture for easier starting in cold weather.
The 2589S WCFB carburetor is compatible with a variety of fuel systems, including mechanical and electronic fuel injection. It also features a number of adjustable features, such as the idle mixture screw, air bleed screws, and main jet adjustment screws, which allow the carburetor to be fine-tuned to meet the specific needs of the engine and driving conditions.
In summary, the Carter AFB 2589S WCFB 4-barrel carburetor is a high-performance automotive component that was designed for use in the 1957 Mopar Chrysler Desoto 354 V-8 engine.
