Your symptoms sound very familiar. Unless you have replaced the original carburetor in the last 5 to 10 years, I would say this is mostly a carburetor problem; made slightly worse by a partly clogged pick up sock in the fuel tank. Any carburetor will have gotten some clogging from the varnish-like residue of gas (and the fine silt that is small enough to get through a fuel filter) while the car was un-used and that is now lying in the tiny passages in the carburetor that percolates air with the fuel just before it gets sucked through the venturi, plus a likely weakening of the spring or bimetal actuator that pulls the choke shut when sitting atop a cold engine. A carburetor rebuilt by a good firm (but probably not one having the lowest price) should help In some cases converting to a manual choke might eliminate the problem; I.E. installing an aftermarket cable hanging below the dashboard that you operate when first starting each morning. How well this works depends on getting the end of the cable attached to the choke plate on the carburetor, which depends on the layout of things on the side of the carb. Also a rebuilt carburetor should still have the "accelerator-pump" feature still working. This pumps a tiny squirt of fuel into the inlet when you push down on the gas pedal. It is another one of the circuits inside the carb that go bad from age, and would work better on a rebuilt carb.
Also a new fuel filter, unless you have replaced that in the last couple of years. The amount of sludge that can be pulled up from an old fuel tank is scary - like something brought up from the Titanic.
