Maurie and Singer guy, thank you. I did change the needle 4 times. I was using Singer needles and the last change was to a Schmetz 90. So far, so good, but I have yet to give it a thorough test (jury duty). I did check the place where the needle goes with a mirror, as I often do since I use so many machines and it's too much to remember, and so am pretty sure the needle is in correctly.
Joe, that's a great idea. I never heard of that before but it is worth a try.
I may be able to do further testing tonight and I'll let you all know. Thanks for the help!
