Elna Supermatic 722010 bobbin case problem

1953 Elna Supermatic 722010 troubleshooting. Recently I have done a lot of repairs on this machine. Some were recommended by experts in the Elna io group a while ago. I completed a set of tasks that involved removing the motor, checking carbon brushes, cleaning up a lot of carbon dust and gunk within the machine, and rewiring the lightbulb. After that work I still had a 'sticky' spot when turning the flywheel and a new problem - the machine was not pickup up the bobbin thread, so I could not test how the machine sewed after my first set of repairs. I resolved the 'sticky' spot problem by cleaning gunk from around the pinion area. Now my flywheel now spins smoothly. It was filthy down there. I also adjusted the timing. But even after doing that, it would not pick up the bobbin thread. I compared it to my 1955 Supermatic and noticed that on the 1953 machine the bobbin case was 'riding up' as I turned the flywheel. This video captures that problem. I did switch the screws that hold the case down between my two machines and that did not resolve the issue. I'm not sure what to check next. This video shows the current problem.
