Yeah!! Another FW 221..... Okay, do you have the manual for it? I had the same problem when I got my first FW.... almost cried because I thought I'd gotten a machine that didn't work. I had the thread going from left to right instead of right to left. The flat side of the needle goes on the left. Try that first.
Also, check how the bobbin is in the case and that you've got the thread coming up in that little hole. When I put the case into the machine, I hear a little 'click' if it's in there correctly. If I don't hear the click..... its an ugly thing.
I've seen some people put a spring on the spool pin. I've never done that. It looks like the thread spool wouldn't fit correctly, but maybe someone else can tell you about that.
And, it sounds like it's something simple.... at least I hope so. I think everyone here will be able to figure it out for you. I have 5 FWs now and every one of them had a minor issue at the beginning.
And, a picture..... can we see a picture?
