fuel issue after car sits.

Gas sits in the bowl of the carburetor. After a couple days it hasn't evaporated. If you need to prime the carb, I would look for a bad accelerator pump. That's what "primes" the carb when you pump it. Some cars will run ok with a bad accel pump, once they're running. Empty fuel filters, etc., don't matter. When a car starts on the pump shot with what's in the bowl, the fuel pump catches everything up.
