I like that machine. Just the other day I was using one of my Kenmores and it wouldn't make a stitch. I rethreaded, checked that the bobbin was in correctly, but it still didn't make a stitch. I decided to change out the needle and guess what. The needle that was in it was shorter than the 15 that it is supposed to have. Where I got that needle from I don't know, but when I changed from my double needle I put the short one in by mistake. Sometimes it is the simplest of things that are wrong. Good luck with yours.
