True to 401A reputation, the stitch selector knobs were stuck. The A-J knob freed up with a little Tri-Flow applied to the camstack follower. Look at the brown fluid on top of the follower to the left in the photo. ICK..The K-Special knob took a bit more persuading. They both move freely now as does the plunger for the needle bar left to right swing. I cannot wait for Friday when I will have time to get this machine all cleaned up. (I apologize for leaving the top hat cam in place for the photo).
