Like Harold said, check for spark right when it shuts down. When engine cools off perform the fuel flow test. When it floods out, are you getting fuel in the air throat passage where the rubber hose connects too? 35 years or 35 hours experience, rule #1 is to not start replacing parts willy-nilly, thru guessing. Root cause problem solving is the proper procedure for any problem. All major components were designed by Ford to be rebuilt over and over and should be your first choice rather than buying anything made new today. Have you pulled, cleaned, and rebuilt the OEM carb recently? If so, was float set at right height? I suggest to go back to the three basics - spark and fuel but I don't think it is a compression issue so concentrate on the first two.

Probable NO-GO fuel issue causes are: plugged vent, plugged screens, plugged sediment bulb, dirty gas tank, dirty carb, and more. There are three OEM screens in the fuel system. Two are on the Sediment Bulb Assembly; the 3rd is on the brass elbow inside the carb where the fuel line connects to. SEE PICTURES. Do not shove anything, wires especially, up into the sediment bulb assembly. You have a vertical fine mesh screen on the inlet port inside the tank that you can damage. Best solution is to remove the tank and thoroughly clean. There are several possible causes for no fuel flow, not just the carb.
