Tried turning that adjustable vacuum adv can over and over again, and could not get anything more than 3* out of it. So I think the adjustment is stuck or stripped. I took it off and put the old rusty 24* stock vacuum advance on, and used a Crane lockout adjustor for the advance and just set it around 12*-14* to be safe and reset the initial advance to get it back to 10*. I tried two of the heavy springs to see what they did, but the mechanical advance didn't seem to come in even at 1500rpm. I think I had 23* total at curb idle of 800rpm once tuned.

Need to pick up a new vacuum adv can, but this will do for now.
