Yes, I watched that video. We adjusted the height of the pin/shaft that holds the cam stack by adjusting the screw that is under by the light. Stack was reinstalled. I put everything back together, put in a new needle, threaded the machine, and started to sew. No problems. I didn't even have to adjust the tension. I guess after landing in the bottom of the dumpster something moved in the cam stack. Another vintage machine saved.
Thanks!
