Edelbrock's AVS2 Off-Road 650 CFM carburetor with electric choke uses Annular Flow Booster technology and an eight-orifice booster ring to improve throttle response and reduce flat spots in low- to mid-range operation. Designed for off-road durability, it features a spring-loaded needle and seat and an anti-syphon ball to prevent fuel drip, and allows fast part-throttle tuning via changeable metering rods and a Qwik-Tune secondary valve.
