Can one you explain the difference in these two carter bbs carburetors? I have a 1964 automatic valiant 225 wagon and would like to install one of these cart BBS carburetors. I can see the physical difference but not sure which one is for my car. Does it matter? I think the manual refers to one as a spring staged choke and the other a well type choke. The holley 1920 I currently have installed does not have that spring staged feature. So, I am thinking of going with the Carter bbs that also does not have that spring staged feature.

There's nothing significant you'd really need to know. The throttle lever is configured a little differently (the one near the Federated box is a later-production carb with a throttle lever that will work on a variety of '60-'70 cars; the other one will work only on '60-'66 Dart/Valiant/Lancer/Barracuda plus '60-'61 Dodge/Plymouth. There is a minor difference in the choke lever configuration, but it's not important. Yes, the one near the Federated box has a spring-staged choke and the other one doesn't, but they're both for use with the same "well-type" (remote, divorced) choke thermostat.

"Rebuilt" or "Remanufactured" carburetors are usually a losing gamble, but if I had to pick one of these you've pictured, it's obvious more careful attention was paid to the carb near the Federated box, so that's the one I'd try first. The other one has been abrasively cleaned and not recoated against corrosion, which is a sure-fire recipe for severe carb trouble sooner than later once gasoline (which all has alcohol in it nowtimes) begins flowing through it.

The Carter's fuel inlet faces front rather than side; good excuse to do the Fuel line mod.

And if your choke thermostat (the part that bolts to the exhaust manifold's #4 runner) is flabby, the pushrod is bent or broken, or it's otherwise not optimal, get a #1231 Electric choke kit.

Thanks SlantSixDan.

Do you know of a new ball and ball single barrel remote choke that would work for my 1964 valiant wagon 225? Would I have to modify the linkage? Please point me in the right direction. Thanks.

Good new carbs are a lot harder to get hold of now than they were even just a couple of years ago. I'm afraid I don't have any rabbits to pull out of any hats; I sold off most of my small mountain of "rabbits" (new carbs) and don't have any 1bbls left that would fit your '64. I do have a honey of a perfect new '69 BBS, but it is not configured to accept the rotating-rod throttle control on your '64; it will only work on a car that has a cable-type accelerator, either as original equipment or because such has been retrofitted.
