Any chance the distributor weights are sticking in the advanced (outward) position? Happens a lot on older HEI's.

Is there a check valve in the line to the vacuum advance, and if so, it it turned around backwards? I saw this on a friend's car after some yoyo mechanic shop replaced the motor and plumbed the vacuum lines their own special way.
