Oh everyone blames ethanol for all kinds of trouble that's popped up since it became a common fuel additive. About the only one with any credance is that ethanol and older rubber don't get along, but even that is a moot point, as rubber parts don't last forever and any car that's actually running well has had them all replaced over the last 20 years or so. There have been many other changes in the chemistry of gasoline to make it work better in modern EFI cars, and part of that makes it evaporate much easier and quicker. A carbed engine relies on some gasoline sitting in the carb bowl. If driven every few days no issues, but if it sits for a couple weeks or more evaporating fuel can leave sticky residue, and if it doesn't evaporate altogether the bowl level goes down and has to fill again, so longer cranking (plus what's left in the bowl isn't as volatile). Nothing to do directly with ethanol, though I bet the ethanol is one of the components that evaporate a bit quicker when sitting a long time. Back to carbs! Yes, obsolete for all but small engines, and yes, it's a good thing -- EFI is so much better for many reasons on a daily driver. But carbs are still great for old cars! It's easier to run a repro than an old one. Carb tuning is a lost art, but if you tune any carb to the engine it's on it will run well. Hard to get tuning parts for many though. IF I were going to run a different carb it would be one of the Webers -- they are the most tuneable carb around, one reason they are still around! A 32/36 with a 1-2V adapter would be a bit tall, but would work fine on a 232. Yes, the adapter is a restriction, and a 2V intake would be best, but it will function well on the adapter. You would likely have to convert to cable operation as it would be difficult to make a linkage work well. It's not hard to find a 1980+ AMC/Jeep 258 2V intake and exhaust manifold, and that's what I'd do FOR A DRIVER. If you're restoring the car you've little choice but to keep the original carb, or a similar repro like the universal. There should be tuning parts (like jets) available for the repro carb, as "universal" still needs some tuning for different engines.

IMO, just rebuild your stock carb:
Judging by your criteria, best 'go to' carb (for you) might be the stock '65 232 2bbl system, all parts will be there to do a complete swap and the stock '65 Carter two barrel has no diaphragm anything to cause trouble on a classic car that sees less than daily use.

I do like the 2 bbl. WCD carb on my 67 232 engine but did have to do some fabrication because it turns opposite to the RBS that was originally in the car.
Thanks for the quadrajetparts.com link. They show the Carter WCD for 50-53 Buick and 56-70 AMC. I guess it has been around for a while.

BTW, FYI, WTF, BBQ, etc, the Carter WCD base pattern is "Small Rochester" pattern, also called "Rochester 2G". that's what the early buick uses. it opens up tens of improbable possibilities in carburetor choice. more seriously though, there are many adapters for it, and some usable carbs. the one-bbl base is the "Carter YF" base, which has many bolt-on possibilities. this is just FYI though (and mmmm, BBQ), as i agree, a good rebuild job is most appropriate here. a quick google search shows that a brand new Rochester carb can be had for $100 on that large parasite, "amazon".
