Edelbrock 1915 AVS2 650 CFM Off-Road Carburetor Manual Choke

The Edelbrock 1915 AVS2 Off-Road Carburetor delivers 650 CFM airflow with advanced Annular Flow Booster technology designed specifically for off-road applications. This manual choke version provides near-EFI-like throttle response and drivability for trucks, SUVs, and off-road vehicles equipped with small block and big block V8 engines.

Annular Flow Booster Technology:

Unlike traditional carburetors with a single brass tube fuel feed, the AVS2 features an innovative annular ring with eight precision orifices that distribute fuel evenly into the airstream. This design eliminates flat spots and dramatically improves throttle response in the low- to mid-RPM range while maintaining strong top-end power.

Off-Road Fuel Control Features:

• Spring-loaded needle and seat prevents fuel starvation over rough terrain
• Spring-loaded anti-siphon ball in accelerator pump circuit eliminates fuel drip during extreme angles and vibration
• No power valves to blow out from engine backfires
• Two-piece design allows float level adjustments without draining fuel or removing carburetor

Easy Tuning and Calibration:

• Change metering rods and springs in seconds without carburetor removal
• Qwik-Tune Secondary Air Valve adjusts with hand tools for unlimited secondary circuit calibration
• Updated primary and secondary booster clusters calibrated for modern fuels
• Superior tune stability maintains consistent performance over time
