Oh one of the things that can really mess you up is when you take the bobbin area apart and clean it, and then go to put it back, be sure that the little tabby is in an upright position when you go to put the plate back on. it gets trapped in between two spots so it stays in place. If this is free wheeling itself, take it off and put it back in the upright position. After all that she will purr even better. Good luck. :thumbup: Jan
