All of these oils do take some time to penetrate on an unwilling machine. Patience (of which I have little) will be a must in this.

It really sounds like it's the vertical pins to me, like Miriam said - as far as the stitch selector not turning is concerned. Can you post a pic from the top? Similar to Joe's photo?
Unlike the 403, no cams are required for full operation of the 401.
The solvent will go down the vertical pins. They're what's frozen.
What is the setting it's currently stuck on on the left side? A - J? I wonder if it has anything to do with the swing of the needle.
I will try and post a picture. The dial is stuck between the A and B. The plate thingy that is controlled by the stitch selector moves freely now. The other side moves freely too. Well I have to use two hands to hold it in position but it is easy to do.
