So, I want to make sure I have this right. It dies after 12-20 minutes. You can get it to restart but it won’t stay running. When it cools down you can start the process over with the same results. Am I right?
Just throwing this out there..... debris in the tank floating around until it blocks the fuel pickup. Went it sets for a few seconds the debris releases until sucked back up to the pickup.ðŸ›
The gas tank was pulled and taken to a radiator shop where they cleaned it and sealed it before I reinstalled for the engine start up. I also installed a new sending unit with the sock filter on it. I also have a glass bowl filter at the carb. So, there shouldn't be anything floating around in there unless it got in there when I filled up the tank at the gas station.
A vacuum/fuel pressure gauge costs less than a good hamburger and fries at a casual dining restaurant, and the vacuum gauge needs to be used every time the idle mixture is adjusted on a carbureted engine. Every FLAPS has one on the shelf with the rest of the basic tuneup tools like feeler gauges and compression testers. I guess it's simpler to make wild-donkey guesses and then bloviate about them.

Not trying to make wild guesses. I just don't have all the tools easily accessible. I was able to locate a gauge like you linked. I got it hooked up with some brass fittings and started the engine. It showed the pump to have a steady 2.5 PSI.
After it died this time I restarted it with alot of throttle. I held the throttle for several seconds and let off. The engine then idled for several seconds before it tried to die again. If I rev'd the engine it would stay running.
