As I put more film through my new S2, I'm finding a few minor issues that may or may not need to be addressed. At 1/1000, the slit doesn't open (no light reaches the film). At first I thought that's OK, I can live without it. But now I realize that at 1/500 the right edge of the image (left side of the gate) goes a little dark. I imagine this is because the rear curtain is closing a little too quickly.
My research so far shows that there are two easy-to-get-at adjustments on the bottom of the camera under a cover plate (2 screws).
Unfortunately the two references I have disagree as to which is which. Nico van Dijk's page

says the rearmost shaft adjusts the tension of the rear curtain.
Rick Oleson's Tech Notes identify the rear shaft as the opening (first) curtain adjustment.
My instinct tells me to go with Rick's much more detailed description on this one. I suspect I need to slow down the rear curtain a little to fix 1/500. True? (Clockwise turn of lens-side shaft?). Does anyone have experience with this adjustment? How much of an adjustment might be needed? How much tension is it under--will it be hard to hold while the lock screw is out and the jam nut loosened?
