Just wondering if anyone recognizes this carb. It is in my 1957 F100. It has a 405 33 DB on the front of the carb body. Sent from my iPhone using The H.A.M.B. mobile app
It looks like the carter equivalent of the Rochester 4 jet. Your '57 would have come with a Holley tea Kettle. That is a swapped in "upgrade"
The pictures don't show everything that would be helpful, but a SWAG would be a modified Carter AFB from a 1966 Buick. EDIT: I don't think any of the 1957 F100 trucks came with a 4-barrel. There was a Holley 4150-G (with governor) available on the larger trucks. The 1957 Ford p***enger engines came with several 4-barrel options: Autolite 4100 Carter AFB Holley 4150 Dual Holley 4000's Oh, and of course the T-Birds had an optional blown Holley 4000, good luck on finding one for less than the national debt! Jon.
Jon's the expert on those things. Most likely it started out on a 61 Buick. That could be a 4053S rather than a 40533 though. Looks like they used and adapter to bolt it to the 292.
How about absolutely no choke and no fast idle linkage. Cannot tell if the fast idle cam is present or not. Jon.
It has the choke plate and shaft, but nothing connected to it. There are some folks who apparently don't understand what all that stuff does, so they remove it....the Muntz approach to carburetor repair. A clear picture of the numbers stamped on the front of the base would help the detectives figure it out.
That would be the "it's a hot rod we don't need no choke to work." line of thinking. Finding the pieces to make it work now might be a bit of a challenge though.
When I posted no choke, my post was technically incorrect, as Jim pointed out in his post. My intention was to state no functioning choke, as the choke housing, and choke link have been removed. While lots of folks DO remove the choke from their hot rod (if it works on a race car, it will be great on the street); tests have conclusively proved that the presence of the choke ****erfly tends to straighten the "dirty" (dirty, as swirling, not as in filth) air at less than WOT, and improves lower RPM performance. When we were still building 2-barrels for the roundy-roundy folks, we left the choke plate in place. We did narrow the shaft to the point it was too thin to hold the attaching screws, and pop-riveted the choke ****erfly to the shaft. This trick, along with others, made a noticeable difference when accelerating out of the corners. As to replacing the missing parts, probably would be easier to acquire a complete carburetor, and use this one as a parts donor. And if I were going to put a single AFB on a Ford (I put TWO on mine ), this is not the one I would suggest. Incidentally, I have the chokes functional on BOTH of the AFB's on my 390. Jon.
I have a piece of baling wire holding each of the chokes open on the 9755 AFBs on the blown 427 in my car. The blower seems to help it not need choke action. Living in AZ helps, too. Fire it up, get a little heat in the heads, and drive.
