Im finally getting back to work on the Jeep (76 5.2 2barrel) 83 engine) and need to address the mechanical issues. Really the only problem I have is the carb - it's shot. It's bad enough where it runs absurdly rich and I see fuel pooling up around it when it's running.
I just want to replace it and need an idea of what to get. Carb posts here seen to mention just buy an original and dont mess with a Weber/Holly/Edelbrock. My complication is i know the engine is not the original 76 and I'm not sure the year. In addition, most of the vacuum system has been pulled and capped - 1 line from dist to carb remains.
Any aftermarket carburetor will need to be tuned to the engine it's fitted to. Aftermarket carburetors provide a lot more latitude in tuning than OEM carbs, and this can either be helpful (if you know what you are doing) or not. How much experience do you have tuning engines?
Unless you change to a different manifold, you should stick with a 2V carburetor. New replacement OEM carburetors are being made for these Jeeps, with varying reports of quality. The only 2V aftermarket carb I would consider is the Holley 2300 series, which comes in 350 and 500 CFM versions, for street or marine use. Lots of accessories and tune-ability, but again you'll need to step up and deal with configuring it for your engine.
OEM carburetors are constructed from the factory to work and be in-tune for the original application. Minimal flexibility, but they don't need any since they are for a single application. The original 2V carburetor is shown in the 1976 TSM here: https://oljeep.com/edge_parts_man.html There is also an '82 TSM there, which will be very close to the year of the engine. The vacuum system and devices are also detailed. I predict if you put the '76 carburetor and devices on an '83 engine, it will run fine, and vice-versa. You should also be able to run an '83 carburetor with all the '76 plumbing and it will be fine. Look for a tag number on the carburetor.
If you have the original carburetor, an actual carburetor shop can rebuild it. It's also not that difficult to rebuild them yourself, if you are up to it.

So a quick update. I found a local guy that specializes in old carbs and would rebuild my carburetor. Tore it off and went to take it to him. Then covid happened. after waiting a month and realizing he was never going to get to my carb I decided to order a cheap car from Amazon for $90.
Bolted it up and it worked perfect. So far so good. Runs like new!
The plan is when Covid is gone, I'll get this gentleman to rebuild my original carburetor and reinstall it. Until now my American muscle will be fed by Chinese crap...
