Hard Starting After Warmed Up.....Arrrg

Rob.. the motor is plain jane stock from what i know about it with the exception of the intake, carb, and headers.

If I block off the vacuum advance and set timing for idle at 12° , when I plug the advance line back in and read the total, the timing is over 40 at 2700-3000.

Am I missing something...???

I guess not.
