I’ve rebuilt so many Autolite 2100/4100 carbs over the years, I could probably do it in my sleep!
Another trick. Get a gallon can of Berryman’s Chem-Dip. Last time, I got it at Walmart. Just dunk the parts and in 10-20 minutes, the crud is easily removed.
Also, I usually switch the choke thermostat out for an electric one. The mid 70’s Autolite 2100 electric choke will bolt right on. Sometimes there’s interference inside, but if that happens, I use 2 of the ring-style gaskets. Then I hook it up by running a wire to the stator lug on the alternator (if you look at a mid-70s Ford wiring diagram, that’s where they connected it). Put in a fuse for added safety. Most likely, the heat tubes will have already rusted off the exhaust manifold. I just cut the hot side off an inch or two from the choke, and run a hose up to the fresh air connection on the air horn.
The only car I haven’t converted is my 64 Galaxie with a generator. I haven’t tried this yet, but I read a suggestion online to swap the oil pressure sender out for one from a 70’s Chevy Vega. It’s supposed to have an extra lug you can use to power the choke from any 12 volt connection, and only supply power to the choke when the engine is running. I’d put a fuse on that set-up, and maybe try a Holley electric choke thermostat that’s meant to run on 12 volts.
