I Just got a Singer 128-13 today at an auction. It runs, but can't get the threads to stitch right. It has a manual, but no attachments. I was going to take it to our local sewing center to see if they could get it working right. Will that work? Is it easy to get them tuned up and working, or do they need to go to some place special - to get parts etc. ?? Any help will be appreciated. Linda
