fire in the hole... after sitting
I would start with making sure the motor turns easily then cleaning down the motor/ engine compartment. It's a much more pleasant experience and things are more easily seen when you drop something.
I would soak down with penetrant the carbs, manifold nuts, etc. at least twice. ( Don't want any studs breaking off.)
I would carefully remove the plugs and document what they look like. Black fluffy deposits, oily, nice and tan which indicates how healthy it is or was. I spray some oil down the cylinders just for grins.
I would pull the radiator and back flush it 2 or three times. Squeeze all the hoses- crunchy? Replace.
I would look over each part of the ignition, points etc. and if everything looked good, cleaned, reset, and static time the ignition.
Fuel pump- can be operated by hand on the bench. if it pumps, it's good for now.
BEFORE stripping the carbs, note the adjustments and write them down. Don't touch the throttle screw adjustment. You're just cleaning and making sure the jets, float, etc. work. If there's "white rust" in the float chamber- dremel with a wire brush. If the throttle plates are stuck- penetrant wiggle, repeat.eventually they all break loose. DOn't take the plates off the shaft. You just want to make them operational.
Gas-Steve talked about the tank already.
Before starting- remove the coil wire and crank it to get some oil moving first. if the oil looks decent don't change it just yet. A new filter would have to be filled and you want oil pressure fast.
Gas II- pour about 1/4 of a paint can top down the carb.
Put the wire back on the coil and fire it up. You just want it to run for a minute or less so you can look around and make sure nothing's leaking, smoking, etc. All ok? Fire it up and watch the temperature to make sure nothing gets too hot. ( T-stat-)
Once you've satisfied yourself it can run good or bad, then you can go back and tune/ replace parts, etc.
Carbs and your picture-
1. Don't try to take the chokes off by the hoses. Cut the hose and slit it. Those little nipples can get brittle so be careful. I usually remove the choke by the three screws on the ring. The bolt on the end- there's a rubber o ring and a copper washer below. Hardware store. But be carefull when taking it off.
2. You have some emission controls still on the car. Time to decide what you'e going to junk and plug since they're not available.
3. Everyone decides to disaassemble the carbs more than necessary. It's better to clean and check each function first. If the float valve works don't take it apart for example. Save your gaskets as you take them off for comparison.

Good luck.
