Runs then dies

Yeah, 10" of vac & mild cam do not belong in the same sentence.
I have run 10 psi of fuel pressure with a TQ at the track & never had a problem; fuel pressure was raised to raise fuel level slightly to change the tune.

30* of initial timing might well be what this engine likes with only 10" of vacuum.


The BIG clue: rebuilt carb. In this case a TQ. Strip it down & blow out the passages.
Check:
- idle mixture screws are adjusted when engine is hot
- choke blade is vertical, not loose when warmed up
- floats are not fuel logged
- floats are not binding
- float level is correct
- needles & seats not leaking
- the two o rings are in place under the primary booster legs. Replace if in doubt
- check [ for leakage ] the two black pods expoxied under the black body, under the pri jets. Leaks here can cause strange happenings....If in doubt, remove existing expoxy & re--seal. I do every TQ as a matter of course.
