I called my local carburetor legend and was told not to bother with the Holley 1931 as it's now obsolete. I don't know how much I believe that...but...
What is the go to carb in the AMC world for the 232? He recommended I call Daytona Parts and get their universal 1bbl. I would like to keep the original style linkage. Would also like to keep a somewhat original appearance.

You didn't state what year we are talking about. If it is mechanical linkage its going to be extremely difficult to change out the carb.
I saw one of those universal carbs made in Chile for a jeep on a car in Cordova. Due to the height he had a custom built air cleaner and the linkage changed out to cable. Said it worked great. Having AMC Fun, Ollie

If you deal with one of the antique carburetor guys like Mike's Carburetor Parts you can get a kit and some of the other parts for a 1931. Yes, there might be wear in the carb body which might or might not be correctable but the proper carb kit and a good cleaning can correct a lot of problems. As Ollie points out, the mechanical linkage can present problems when you are switching to another style of carb. Joe

yup, the holley 1931's obsolete. lol, as are all carburetors! pending your linkage issues, the dumb old Carter YF is abundant, very well known and should have no problems with parts. i will second the warning about worn out bodies. often it's hard to tell, but obvious pitting in the venturi or bore, or anywhere gasoiine wets the metal on it's way down. if the throttle shaft is loose it's gonna really screw up setting idle. |

All carburetors are obsolete and that is what is great about them. Obsolete fuel delivery systems for obsolete engines in obsolete cars. It's just right and the 1931 is as good as any. Replacing it with a different one barrel like a YF, 1909, RBS, 1100, or Monojet is simply futile and almost guaranteed to not run as well as the original 1931 since your particular 1931 was specifically made to have the proper calibration for your year and configuration of 232. Most any other carb would not be and you cannot recalibrate it as well as the manufacturer did.
The original carburetor for my 360 went missing decades ago. It came to me with a Ford carburetor on it. Same basic carb: a Motorcraft 2100, but calibrated for a Ford and not an AMC. It ran ok, but just ok. I located a proper AMC 2100 for it and it runs so much better now. The original carburetor for my 232 was removed just a few months before I bought it and replaced with a professionally rebuilt one from an engine several years newer. It was so darn lean all the time. I had to do tons of recalibration to make it run well. Really wish I had the original carb. The original carburetor for my Buick 231 V6 was replaced with an "equivalent" auto parts store remanufactured replacement decades ago. I never knew how good that car could run until I located the original carb and reinstalled it. Wow it ran so much better. I go to long lengths to keep my original carbs going. I'll part out a better condition carb to use the parts on my original carb. I'll bush throttle shafts. Anything to keep the original fuel delivery calibration. They just run better. "Universal" is another word for "runs terrible on everything". For a carburetor that really runs well with crisp response, the original carb is he easiest way to go.

I like to have the original carbs, but not always ideal... A universal carburetor can be made to work well. Hot rodders have been doing it for decades. The edelbrock and Holleys are 2 examples

If you are running an old carburetor and want it to last longer don't put ethanol fuel in it:

we don't often get a choice of what's in fuel... and i'm skeptical of the 'aluminum ethanol' thing; that's one post, and there's millions of aluminum engines and aluminum carbs out there. and aluminum+alcohol meeting didn't start recently. i agree with FSjunkie on the original carbs being likely better dialed in than some random part. but not all of AMCs choices were exquisite performance; it's also a matter of what's available, cost, etc. i would love to know how well they were actually tuned (some hand-written notes of A/F ratio at various points would really, actually, be interesting). it's an open question as to how much 'state of tune' would change by substituting the various 1bbl stock carbs, YF, 1961, RBS, etc. i'm sure there are differences but seriously, these weren't ever finely tuned. they can't be; the same car was sold in Los Angeles, Denver, Phoenix, etc. PS: lol, speaking of carbie-burettors, today i had a massive breakthrough day, tuning my new Weber 44IDF. a bag of jets, A/FR meter and 100 miles of highway, i got it DOWN -- feel and see the crossover from low-speed to main jets, fiddle air correction to increase richness a bit high speed (sic). aren't carbs fun? |
