My 301, AnnieRose, is back to normal. My son took her apart and sewed with her. He was able to pinpoint the dry area. A dot of oil and she's happy. I oiled her before I started this quilt, but whatever. It was on the left end of the cross bar. No where near where it sounded like with the cover on. The gears do not need grease.
Now if I can find where the broken plastic washer came off the Stylist, we'll be all set.
