I have just bought a Singer 257 Fashion Mate machine. It has what I think is a timing problem. The needle catches on the race in which the bobbin sits. I cannot work out how to solve this. Can you advise? I live in rural France and there are no sewing machine mechanics near me.
Also, the working parts in the top of the machine are covered in a thick, heavy, sticky grease and that seems all wrong to me. What can I do?
