leonf...huge thank-you for your very detailed advice. I had waited to respond hoping to be able to tell you I got the wheel free to turn. I have not messed with the screw on the wheel but I guess that's next. I had hoped with oiling and just working the wheel for a couple of days would loosen it up. When I first started messing w/ it the needle bar didn't move at all, it now slightly moves but still not completely fixed.
