The inside was needing some clean up. The plastic gears were intact so I dug in on it - why not give the poor machine a chance. The stitch selectors were gummed up but I got them free thanks to T-F and some heat. It took quite a bit of clean up to keep the selectors moving. The underside of the machine looked like it was starved for oil. The tension was a little filthy so I took it apart and rebuilt. The bobbin winder was fine. So I test sewed. Perfect. Wow. I'm thinking this one should chain stitch. It is a lot like the 401, 500, 600 etc but noisy due to the plastic gears. Then I had another T&S machine Wilbur started cleaning yesterday. It was sort of like the 403 and 503 in that you have to use disks for anything other than straight stitch. This one was fairly clean inside and out and runs fine. Seems there are some T&S machines out there that are fine.
