The AFB6566 is a 4-barrel carburetor, which means it has four individual throats or barrels that feed air and fuel into the engine's intake manifold. This design allows for a larger air and fuel mixture to be delivered to the engine, resulting in increased horsepower and performance.

This metering pattern allows for optimal fuel delivery at various engine speeds and load conditions, ensuring that the engine receives the correct amount of fuel to run efficiently and produce maximum power.
The AFB6566 features a vacuum secondary system, which means that the secondary throats only open when additional fuel is needed, such as during acceleration or high engine load conditions. This system helps to prevent fuel waste and ensures that the engine only receives the amount of fuel it needs to run efficiently.
The AFB6566 is also equipped with a mechanical secondary choke system, which is activated by a vacuum switch located on the engine's intake manifold. This system allows for smooth and consistent engine starting in cold temperatures, ensuring that the engine is properly warmed up before being driven.
The AFB6566 is made of high-quality materials, including a cast aluminum body and brass components. This ensures that the carburetor is durable and able to withstand the rigors of high-performance driving. The AFB6566 is also easy to adjust and tune, making it a popular choice among enthusiasts who enjoy working on their own cars.
