What might be a quick simple test to see if it is a Vaccum Advance as I suspect or a Vaccunm Regard would be to pull the vac tube to the dist with the motor running at idle. If rpm's increase when it is removed, it is a Vaccunm Retard and I am mistaken.

If RPM's fall when the tube is removed, it is a vacuum advance pot and is hooked up incoreectly.

If the RPM's stay the same, it is probably a Vacuum-Advance pot as I suspect.

If you hook a tube to the dist vac connection and suck on it and the RPM's increase, this also confirms it is a Vacuum-Advance pot.

Good luck.
