The Carter AFB 440 Auto Charger RT Carburetor, model number 4738S, is a legendary piece of automotive history, hailing from the golden era of muscle cars in the 1970s. This carburetor is an original equipment part for Mopar's 440 cubic inch "Elephant Motor," which was renowned for its power and performance.
The Carter 4738S is a two-barrel carburetor, designed to deliver a smooth and powerful air-fuel mixture to the engine. The barrel itself is made from high-quality materials, ensuring durability and reliability even under high-stress conditions. The barrel features a unique design, with a rectangular shape that is characteristic of Carter's Auto Charger series.
The carburetor is equipped with a Quadra-Jet secondary system, which utilizes four small jets to provide a fine fuel atomization for better combustion. This system, combined with the carburetor's Accelerator Pump, ensures a quick and smooth throttle response, making the car responsive and agile.
The Carter 4738S also features a high-quality Air Fuel Ratio (AFR) meter, which allows the driver to monitor the air-fuel mixture in real-time. This is particularly useful for tuning the carburetor to optimize engine performance. The meter is located on the top of the carburetor, making it easily accessible for adjustments.
The carburetor is also equipped with a vacuum secondary choke, which helps to improve cold start performance. This is particularly useful in colder climates, where the engine can take longer to warm up and produce enough heat to ignite the fuel. The vacuum secondary choke ensures a smooth and easy start, even in cold conditions.
The Carter 4738S is a direct replacement for the original carburetor on 1970 Mopar Barrel AFB 440 engines, and is a popular choice among enthusiasts and restorers. It is easy to install, requiring no modifications to the engine or intake manifold, and is backed by Carter's reputation for quality and reliability.
In conclusion, the Carter 4738S 1970 Mopar Barrel AFB 440 Auto Charger RT Carburetor is a must-have for any Mopar enthusiast.

Correct for 1970 440 HP auto cars but will obviously fit many other applications. The carb is in used condition. It obviously needs to be rebuilt. Shipping is a flat rate of $25.00 in the US, $75.00 to Canada and $145.00 elsewhere.
The item for sale here is a 4738S AVS Carter Carb. It moves freely and is complete with choke. One of the idle adjustment screw holes has broken aluminum on bottom it, not sure if its fixable or this is a parts carb.
