Alex,
You asked about that mysterious little screw on the back of the trommel. I don't know what it's for either. Wouldn't it be nice if we could see inside the trommel? When I first got my SNO-T I tried to take the trommel off in order to clean it, but couldn't drive out the little drift pin that positions it on the end of the index arm. Perhaps that was a good thing.
I have less riding on my SNO-T than you have on yours, since I have the Tamaya. So I've given that screw a few turns to see what happens. Turning it in makes the adjusting wheel turn too easily, backing it out tightens the wheel. As you can see the screw is set in at an angle, as if it were pushing on one end of a split ring. It doesn't seem unreasonable to suppose that backing this screw out a bit might lessen backlash. But I really don't know what I'm doing.
