Bob, that early a carb did not have an accelerator pump, to get them started one usually had to use the choke. How is the compression? If it is really low it may not be pulling enough air to draw fuel into the manifold. Or the valves could be getting weak. Gas was drawn from the carburetor bowl through the metering jets in the venturi by air moving through the venturi, in other words, vacuum. You're sure the carb is not plugged up? Have seen old engines so worn that it took a squirt of oil in each cylinder to create enough pressure for them to fire off. John in Nebr.
