Today we are addressing a stop motion knob that will not turn on your Singer Featherweight 221 or 222. Loosening the stop-motion knob is necessary to wind a bobbin, but being able to tighten it so that regular sewing can resume is just as important.

1. Handwheel washer is positioned incorrectly.
2. Stop-Motion Knob has been overtightened.
