I am ssssooooo bummed out. I just brought home a new baby. She is a Spartan. I checked and checked and checked and I can't find anything wrong with her. No lint, no caked on oil, her tension works fine, her bobbin area is immaculate, she sews a very nice stitch. Nothing for me to do. sigh. No, I'm not really bummed out. I'm thrilled. She takes the same bobbins the Singer 403 I use a lot uses. Well, she does have 2 flaws. A little scratch or two in her paint and the top of her case needs to be re-glued. She does not own a light. She came with a slant zipper foot and a button in her mostly dust free box. Oh and her wires are NEW and her bobbin winder is NEW and her belt is NEW. Her motor runs flat out fast.
