Edelbrock Carburetor AVS2 Series 4-Barrel 650 CFM Off-Road Electric Choke Satin Finish (Non-EGR)

The Edelbrock AVS2 Off-Road Carburetor features an annular ring with eight evenly spaced orifices, replacing the standard single brass fuel feed tube. This design distributes fuel into the airflow with an even spray, which helps eliminate flat spots and significantly improves throttle response from the low to mid-RPM range without hurting top-end power. It's a special 650 CFM version of their well-known AVS2 street carburetor, built for those who need reliable performance even when the terrain gets rough.

For superior fuel control off-road, this carburetor includes a new spring-loaded needle and seat, along with a spring-loaded anti-syphon ball in the accelerator pump circuit. This setup prevents the fuel drip that can happen with standard carburetors when you're bouncing around. You also won't have to worry about engine backfires blowing out power valves, because this design doesn't use them. Tuning is made easy with metering rods and springs that can be swapped in seconds without needing to remove the carburetor or drain the fuel. The AVS2 Off-Road carbs are known for holding their tune, meaning your adjustments stay put and performance stays consistent.

Updated primary and secondary booster clusters are calibrated for today's fuels and octane levels. The unique Qwik-Tune Secondary Air Valve allows for extensive calibration of the secondary circuit, adjustable in seconds with simple hand tools to match your specific application. The two-piece design makes tuning and internal component access straightforward, as you can make float level adjustments or replace parts without draining the carburetor or removing it from the engine. This particular model, #1916, comes equipped with an electric choke for quick starting.
