I just called a sewing machine repairman to inquire about getting the screw and spring, and ,is it bushings too, for my 1924 Singer 99. What I have is a screw/top missing from my motor and the spring sticking up. The machine does work even though the spring is sticking up. I asked him if he had the screw or whatever it needed, and he said that I'd need to bring it in. He said it needed the bushings, etc. I asked him how much it would cost, and he said $30-35.00. I asked why so much, and he replied "for the parts and labor, and it won't work unless it is put in right." Is it that hard for me to order the things from some place like Sew-Classic and put them in myself? I hate spending $30-35 if I don't need to. Thanks!
