Thank you for both your help. While getting all the insides clean and polished may be best, I believe its beyond my capability at this time. I'll be happy with it making a good stitch even if I have to oil at every use for a while. Eventually all the ick will come out. In my opinion I've accomplished a lot considering this was the first time I removed any screws, not to mention a major one that controls the entire machine. She moves so I'm happy at this point. If she moves after I get the big screw back in I'll even be happier. When she makes the first stitch in who knows how long, I'll be ecstatic.
