Singer 99-13; stitch length adjustment, how to?
I'm working on a Singer 99-13 (1925 vintage) and the machine clatters like crazy. As best as I can tell the feed dogs are hitting at the rear of the slots on the needle plate. I have a ton of reverence material, and not one has actual instructions on how to adjust the fore and aft position of the feed dogs. Several mention it, but no instructions.
I don't want to over do the adjustments, I just want to move the feed dogs a bit forward so they don't contact the needle plate.
So anybody got a source for instructions for this adjustment?
