I just fixed a feed dog issue on this and stitched about a couple of feet of zigzag and then it started making strange noises like the machinery quarreling with itself so I stopped. Since then I can get it stitching happily, no strange noises, plain stitch and even zigzag - except the zigzag does not zigzag. It just come out plain. No zigzag type stitch will work it seems. The zigzag function has gone.

Where do I look for this, anyone know?
