Scott, I watched the diaphragms as the vacuum pulled back on the linkage, there was no apparent changes to the diaphragm, buckling or stretching that I could observe. No I did not measure anything, I'm not equipped to get that detailed in my garage.

My initial thoughts were that the diaphragm was being stressed by the sideways motion of the arm, but that is not the case as far as I can determine. When the diaphragm first starts moving the arm does move as it centers itself, but it does that in either case, after that the arm moves in a linear path, no sideways movement at all. There is a slight vertical movement due to the arc of the bellcrank, but again it is the same in either case.

If there is anything else you can think of to test, I have everything exposed now.
