I found a qjet, should have it soon, while I am waiting I decided to use a different Carter , I had my old Carb the 9635SA or the 1405 which is the same.
I tried to change out the venturi's and squiter and jets rods to a 389 pontiac it didn't fare so good, the idle was real rough. I found in the carb a passage that's part of the idle circiut blocked, cleaned it out and went back to base Calib. and decided to try it and I had a bog at accel. off idle so I tried the rods out of a 1406 just the rods and WOW, I got a chirp when I released the brake and punched it and no bog even when the secondaries kicked in, just trans shifted hard into third, but WOW.
This carb the AFB 9635SA almost performed as good as the AVS does.
