Are you sure that moving the horizontal dial isn't setting the distance for the zig zag (which will move the needle)? I had a 1630 years ago and I don't remember a dial to move the needle. I only remember 2 dials. One to set the stitch length (vertical) and one to set the stitch width (zig zag). I can't remember off hand how to move the needle. My 180 has 2 buttons that move the needle left and right.
