Thank you for taking time to reply. I don't know how to post pix. However, I also have to admit that I was wrong when I said it was not locked up. There was a part that was absolutely fused and I had no idea it was supposed to move or that it could affect what I was looking at. Once I got it moving again, the machine goes forward. A victory!
There are still other issues, but I know now to check other areas likely to need cleaning and oil. I was too frustrated to continue so I put it up for a while. Even so, it is a wonderful machine.
