If it were my car I would do the following.

Rebuild carb, cost of kit for Zenith about $60.00 US.

Do a complete tune-up, points, plugs, rotor, condenser, and cap. Set plugs at 35 gap.

Make sure your air cleaner is not obstructing air flow to carb. You might want to try running without the cleaner, although I would use one.

After you start your car and it has warmed up, the richness control on your choke should be turned back to about quarter turn from off.

Off turning to the right, open turning to the left.

When we are done running car we turn control to off position. Do not snug it down, just lightly turn to off.

Our car starts when cold, open 3/4 turn, than once warmed up, turned back to 1/4.

My comments are based on not knowing how and when this was last done. A good tune-up goes along way. Plus we have no idea what condition your carburetor is in.
