Not being sure if the vac advance was working propery, I detached the tube at the carburetor end and tested with a mighty vac tool. There appears to be constant leak down.
Before I shell out the iron men for a new one, I thought I would ask what might seem like an obvious question: It is not supposed to leak down at all, right?
The reason for the question is that on some (newer) cars that used a lot of vacuum operated engine controls, some devices are SUPPOSED to have a calibrated rate of air passage.
