I want to say thank you to all who responded to me and to that link ArchaicArcane sent me. I decided to try to take the bobbin case base out. It took quite a while, but finally got it out. It was stuck and after I cleaned it and oiled it, it started to turn with in the case. That was why the needle would not work when the throat plate was on.
So glad to have it working. No w I just need a bobbin case and I can start sewing.
