Problem solved!
It was a bent presser foot.
I was working on another 401 that has set in the bottom of a closet for years to give away. I can't seem to get the problems solved by the time I promised, so I'm giving her mine. I was double checking that everything works and remembered the left drifting foot (not a good idea for a new quilter). I tried another foot and it didn't pull. So, I looked closely and tried it again. It drifts and is bent.
Thanks,
