This morning I cleaned, oiled and lubed the Singer Touch & Sew Model 628 that I got from my MIL. I sewed on it a couple days ago and it sewed ok just seemed noisy. I figured it needed some attention. I also have a Singer Touch & Sew so I figured I knew what I was doing and I had the book to follow. Well, after my loving care the tension is off. I usually have mine set around 3 and I had to move this one down to 1 and then it still doesn't seem perfect. The inset bobbin winder does not work because the little button will not stay down, but that is something I don't know how to fix so will have to take that to a shop. Any suggestions on the tension?
