Thanx for the Air Valve Adjustable Secondary non explanation that has so little to do with off idle issues unless the door is so damn loose or the spring is broken

Anyways


I run my own Rebuilt Tweaked Factory 1971 Carter AVS that performs flawless


I also have installed a few current Edelbrock AVS series carbs on friends cars that had off idle issues flat spots that I had to change a few things that I was able to fix that are light years ahead of the Performer Series line that I threw everything at



Why would they update the current line of AVS Series Carbs already ?



650 CFM, MANUAL OR ELECTRIC CHOKE
(THE ULTIMATE PERFORMANCE CARBURETOR)
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.
