Featherweight problem
The belt came off the large wheel on my FW, so I removed the screw in the small wheel and pulled it off, then moved the belt back in place. When I went to put it back together, I think the stop motion clamp washer was in the wrong position, so it wouldn't sew. I've taken the screw out again, but can't unscrew the little wheel to get it off again. What should I do? I've been using the free Singer Service Manual, which makes it look really easy, but obviously I've done something wrong. Can I do this myself or will I need help?
