I cleaned my Spartan this morning, not a "Billy" clean, but just an oil and goop one. This one must never have been cleaned of lint in the 51 years of its life. Threaded it, wound a bobbin, and sewed. I'm not real sure on the tension as I need more practice with this part. My problem comes in with the stitch regulator. I can turn the knob and move it up and down and then turn the knob to set the stitch length. When I sew the vibration makes the knob move up and the stitch length gets shorter and shorter. A couple of the braces it sits on is chipped so it does not sit square in the base but I think this has nothing to do with the stitch regulator and the vibration of the machine. I really like this little machine and it is another one I will definitely sew on. So any help is appreciated. Think I will now go pick Blackberries. :lol:
