Can't release the stop motion knob on FW
On a FW I was gifted, I cannot get the silver stop motion knob to budge at all. It should release by turning the knob counter-clockwise while holding the hand wheel but the knob will not turn at all. Thought maybe someone had just tightened it a bit much so I tried using one of those rubber jar opener gripper things but still couldn't move it. I tried removing the screw that holds the knob on but, even with the screw out, I can't move that knob - neither turn it nor pull it off. The machine runs beautifully but if I want to wind a bobbin I can't stop the needle from moving up and down if I can't release that knob.
Any ideas?
