I am sure this is covered in many other posts but this one is current. I am very curious here because I have been working with the timing and idle on my ’82 also. The factory manual clearly stated to disconnect the vacuum lines, when setting the timing, it doesn’t mention plugging them. My SC has both the advance and the retard on the distributor. When disconnecting the retard the idle increases, isn’t that what the retard is suppose to do?

So then when timed, plugging in the retard line drops the idle, as it should I think, and then resetting the idle. In order to get the idle up to the 900+/- I have to back the set screw all the way out to the stops. This doesn’t seem to be right.

So first off, vacuum disconnected, yes or no, when setting the timing at both idle and at high RPM? Plugging the lines when disconnected doesn’t seem to make a difference at idle, I haven’t tried at high RPM’s.
