If so The AFB's used an internal counterweighted door above the secondary butterflies. it can be adjusted by adding or removing weight which is a PITA The AVS's used an adjustable air door on the air horn ( top of the carb). www.tandmautomotive-omaha.com

Huh? The secondaries are opened mechanically by a link rod from the primaries, the only spring involved is the one in the primaries to prevent the secondaries from opening when the choke is closed. The use of the weighted air flapper in the secondaries is yes/no; some had it, some didn't. The INTERNET, the MISinformation superhighway

I think its suppose to keep the secondaries closed when the primaries are a little open. I have to look at mine again but the other night I opened the primaries full and the secondaries did not open.

AFB came out in 1960 ?? so you have early AFB carbs.

Not so Pontiac, Ford and Mopar and other GM motors used Carter AFB, Aluminum Four Barrel starting in 1958, that had the weights on them Some of the smaller C.I. AFB carbs. did not have the weighted air valves under the rear secondary venturi boosters, but some did :shruggy :Most of the bigger C.I. motor carbs. had them stock The Carter Air Valve Secondary, AVS carbs, had the spring loaded door above the secondarys starting in 1968, maybe also the 1967 HP 440 motors, on the HP Mopar motors.

As far as Chrysler,the weighted air valve started with the dual quad motors in the 58 Fury/D500/Adventurer and 300D and continued through all inline 2x4 systems including the Hemi and various single fours depending on application.

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...

Well one of my older repair manuals that covers 1950 to 1960 which is a very good book with alot of info has some AFB pics from Ford that have vacum actuated secondaries which is the first time I ever noticed a vacum diaphram unit bolted to the side of these AFB's and hooked to the secondaries. I have never even heard of vacum secondary AFB carbs but there it is in my book ! Well of course they wont use a secondary weighted air valve. And I saw more of the Rochester 4GC mechanical secondaries which had weighted secondary air valves also. And the Carter WCFB carbs like on the Hemi's in the 50's are also vacum operated. I still did not find any pics of the AFB without either the weighted air valve or vacum secondaries. I do believe you all who have the AFB's without the air valve but I myself have just never worked on one without the air valve. Course I have never worked on a vacum secondary AFB either.

Or the tag if it has one? "The only thing to do for triumph of evil is for good men to do nothing" "NUNQUAM NON PARATUS!"
