Video Of Shutter Problem
From this video, you can see the main arm goes to the left as it should, but it is not going far enough to catch on a locking lever, and so it returns to it's resting position, and the shutter does not operate. As far as I can tell, it looks like the charging lever at the top is not moving far enough to rotate the main arm into proper position. I'll have to find an adjustment for that.
Of course, at this point I don't know what is keeping the shutter blades in the recess, so I'll have to do some more disassembly.
