Runs then dies

Should be no mechanical at idle, vacuum unhooked and capped

He's talkin about total when the advance is there. Normally, they have "about" 20* mechanical advance. That's 50 total, plus "whatever" the vacuum can pulls in....if you're running one. Whether or not this is your problem, remains to be seen. How much heat does it have in it when it dies? Is it up to operating temp?
