This is wrong. Not sure how it got so wrong, but it is. I have read opposite explanations of what CW and CCW accomplishes, but what mine does is pretty much opposite of what I typed. Full CCW on my 11R marked can locks the vacuum out. At least to the point of putting 20" to the can.
There is no movement of the pickup when adjusted to full CCW up to 20".
My can took 7-3/4 turns to get to full CW. At that setting; advance starts at <1", max at 8".
Adjusted four turns CCW from minimum; advance starts at 8-1/2", max at 14".
Adjusted six turns CCW from minimum; advance starts at 9", max at 12".
I hope the earlier post didn't lead anyone astray. Best choice in any case is to hook up a vacuum pump and compare values to pickup movement. Smart, particular folks have bothered to put a degree wheel on their distributors to get ยบ numbers. I am more interested in where/when the can starts and ends.
