All the AFB's I have worked on over the years had the weighted air valve and I thought all AFB's had it. Ron I'm not doubting what is being said here but without the air valve I would think there would be a substantial bog when the secondary's were winged open as there was no secondary pump shot In my experience with the AFBs without the secondary air valve there was no bog. Either there was enough engine to keep air flowing OR the carb was small enough by comparison. BUT, put one of those on a 273 and there was a bog...

Hmm, the 413 I had my AFB on was stamped HP and it had no weighted air valve. They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

Those type carbs, same as 1962 and 1963 M.W. carbs, used the big center screw to set the idle RPM No screw on the sides to set the idle rpm All(3) the Carter AFB I've seen that didn't have weighted secondary air doors had the venturi boosters come in from the sides of the carbs, not in from the rear of those carbs. like most of the other carbs do BTW, for some of you younger guys, you haven't seen all of what some of us older guys have seen, I watched the dinosuars die out Mr.Cab Racing and winning with Mopars since 1964.
