I have a Singer Meritt 3130 from about 1992. The cog for that stitch is in the machine. I have sat for sometime yesterday with the owner's manual in my hands and tried sewing this stitch many times after reading the instructions. The needle will NOT go from side to side. I do not understand.
Any thoughts? (Servicing is not an option...$$$). A new machine might be, but it could take a few months to save up.
