Edelbrock AVS2 Series carburetors are the next generation of carburetors. Featuring annular flow primary boosters, adjustable secondary air valves, and a new calibration, these AVS2 carburetors offer improved idle and cruising performance. The annular flow booster design delivers improved fuel atomization to eliminate flat spots that may be encountered when the carburetor transitions from idle to full throttle. Each annular booster features eight, equally spaced orifices to improve fuel metering. The improved flow metering makes this carburetor ideal for use with a wide variety of small-block and big-block engines with either dual- or single-plane intake manifolds.
