Review CARTER Avs 6125s Mopar 383 Carburetor Dodge Plymouth Chrysler Hp

The Carter AVS-6125S is a high-performance quad-barrel carburetor specifically designed for Mopar 383 engines used in Dodge, Plymouth, and Chrysler vehicles. This carburetor is an upgraded version of the original AFB (Airflow Designer Series) 600 CFM carburetor, delivering improved airflow, throttle response, and fuel efficiency.

The AVS-6125S features four 2-gallon fuel bowls, each with its own float and needle jet, ensuring optimal fuel distribution to each barrel. The quad-barrel configuration allows for a wider fuel metering range, enabling better fuel delivery under various engine loads and RPMs.

The carburetor comes with 1050 CFM venturi primaries and 850 CFM secondary venturis, providing excellent idle quality and smooth power delivery throughout the engine's rev range. The primary jets are adjustable from 0.025" to 0.090" in 0.005" increments, allowing for precise fuel mixture tuning.

The AVS-6125S utilizes Carter's Advanced Vacuum Secondary (AVS) system, which incorporates vacuum secondary diaphragms to optimize fuel delivery under light to moderate throttle conditions. This system improves engine idle stability and reduces fuel consumption, making it an excellent choice for street performance and racing applications.

The carburetor body is constructed from high-quality aluminum, featuring an attractive polished finish. The base plate is made from heavy-duty cast aluminum, ensuring durability and stability during operation. The AVS-6125S also includes a rebuildable float bowl gasket, making it easier and more cost-effective to rebuild the carburetor when needed.

The Carter AVS-6125S is a high-performance, easy-to-tune carburetor that delivers impressive power and fuel efficiency for Mopar 383 engines in Dodge, Plymouth, and Chrysler vehicles. Its advanced features, such as the AVS system and adjustable primary jets, make it a popular choice among enthusiasts and professionals alike.
