Product Details

AVS2 Carburetor with Electric Choke, 500 CFM by Edelbrock®. The AVS2 Series is the next generation in Edelbrock carburetors. The AVS2 features annular flow primary boosters with a new calibration for improved off 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 from idle to the main. 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. The AVS2 includes both timed and full vacuum ports for ignition advance. Match with an Edelbrock intake manifold for the ultimate induction upgrade.

The typical downleg boosters (on the left), are located in the carburetor primaries and simply provide fuel down the center of the venturi. Annular boosters (on the right), feature eight equally spaced smaller holes for better fuel atomization. The improved fuel atomization eliminates flat spots when the carburetor transitions from idle to part throttle for better low rpm performance. The annular boosters can also potentially offer improved mileage in some applications.
