Thanks for confirming it is a 66, I had that right at least.. the needle bar didn't move at all even before I disassembled it. I had hoped that all the cleaning and oiling might have loosened it up enough to move a little bit like I said after I put the balance wheel back on, nothing budges except the balance wheel. I suspect that unless I am willing to completely disassemble and troubleshoot, this poor lady is bound to stay frozen...but she's going to look fantastic! I am not ready to take a machine completely apart and even if I was brave enough to try it, I don't have the expertise to accomplish it.
