Uwe, you are a freaking ROCK STAR - Thank you!
This is the second machine you have helped me fix. Along with others, you make this forum something special. And I am sure many people feel the same way.
I tightened up a few pivot points but the real ticket was adjusting the eccentric (cam) on the top shaft under the cover plate. It was pretty loose and the sleeve was floating left and right. To eliminate the unwanted movement I slid the assembly to the right forcing the sleeve against the shoulder of the cam, where it should be. I am not the first to adjust this. The two lock screws are pretty galled. You can see the results in the video. Just the needle bar has movement. It would be nice if I could fix this too, but I can't see any adjustments.
I thought this machine was toast!
Cheers,
Will
