Stop Motion Knob
Suddenly the stop motion knob (the one you loosen to wind bobbins) is loosening while I sew. I can't go more than 10 inches before it loosens and acts like its winding a bobbin. I have tightened it as tight as I can but it won't stop. Its a Janome 1000HD. It doesn't have more than 30 hours of use but it was fine until today. Any ideas?
