Yes I will mark where the rotor is without vacuum advance and where it is with vacuum advance and post a pic.
Below is a pic with vacuum advance hooked up at idle with 18 degrees initial and 12 from the vacuum advance for a total of 30 at idle.
You have to turn the picture upside down and the hole in the cap is directly
Behind the number 1 cap terminal.
To me it looks pretty good, could possibly be a tad better but as long as it's not causing a miss fire I'm not going to mess with it.
But you can see the edge of the rotor is just beginning to come into contact with the cap terminal.
