Here's the skinny: 283 Tri-Power. Starting the car, no issue. Let it run, idle, no issue(s). Drive it around, or let it get good and warm, and the idle slowly drops, and engine dies. Been playing with this for a few weeks, and finally decided to dig in and figure this out. When the problem happens, and the engine dies, (or I shut it off) I can see fuel pouring down the barrel(s), and on the intake from the center (primary) carb. Took it off and apart, and verified that the gaskets are good and all the assembly screws are tight; put it all back together and still does it. Thinking I have a hairline crack somewhere on the body or bowl that obviously gets worse and shows itself with enough engine heat. Thoughts / suggestions? Any way to bench test to confirm?
