Air Valve Secondary The AVS is an acronym for Air Valve Secondary, which is Edelbrock's line of entry-level carburetors intended for mild street engines. This line already enjoys a great reputation among street rodders as a carburetor that you can bolt on and reap immediately success.

Basically, the AVS2 was designed to help your classic engine start quicker, run smoother, and allow for better low-end throttle response – all the benefits of EFI but without the electronics. When upgrading from a traditional down-leg booster carburetor, improved fuel economy is a definite positive!

AVS stands for air valve secondary, which describes the spring-loaded air-valve door. The Edelbrock carb uses a mechanical secondary but does not employ a secondary accelerator pump.

EFI systems are able to run more efficiently and effectively which means fewer emissions and better fuel economy.
