Oops, just saw I typed "quilt" working instead of "quit" working! Guess quilts are on my mind! LOL
Anyway, the power was still good, it would sew, just not correctly. It just wasn't catching the upper and lower threads together, so on a 6" piece, I would only have 2-3 stitches, inches apart, and they would pull out with the least tug at the thread.
The machine is pretty simple, not computerized.
I guess I could take the cover off and check the flywheel. Hadn't thought of that.
