get to the back of the car to tinker with it. BTW the power is OK until
it warms up then it hard to keep it running.

Draining the gas gave an unimpressive flow rate so I pulled the tank and
cleaned the screen. The screen was about half blocked so I figured I
found the problem. Since I was in there, I installed an electric fuel
pump and put a new fuel filter between the pump and tank. Still no
change.


Sounds like crap in the fuel system that has found it's way in to the idle
jets in the carb (assuming carburetor). Not unusual for for a car that has
been sitting for years. Expected given that you found crap in the screen...

Runs OK cold (choke on) not ok warm (choke off) - sounds like carb plugged
up.

You could try a can of fuel system cleaner from the wishfull thinking isle
in the auto parts store, but more likely you are going to end up pulling
out the carb, soaking in parts cleaner, blowing out, etc... before you get
it to run right.
Look for "sea foam" in the "wishfull thinking aisle" - available at
NAPA and other fine auto parts stores - and as fuel system cleaners
go, it works pretty well.
