This IS cheap entertainment. The Kenmore 1217 was binding when the needle entered the shuttle area so I leaned the machine back to see. And then my cousin who is visiting joined in to see. And then my husband joined in to see. Knobs were turned and levers were pulled. The shuttle got taken out, a tiny bit of rust cleaned out of the bottom of that spot, the shuttle got put back in, the binding got better. I still do not really know what I am looking at with a vertical bobbin so I cannot say if its timing is off, yet.
