I would look for a Singer 401 or other slant service manual to see where that spring goes. I know exactly where it goes but I don't think I can describe. It should be a fairly easy fix. You have to hook one end and stretch the other with a pair of needle nose players and you should be good to sew. I'm thinking there should be a link in our sticky notes under resources for working on machines.
