I have been working on a 211G155, I finished setting all the timing of the hook but the cover plate wont close. The plate hits the top of the bobbin.  What am i doing wrong?

I assume you removed the hook. When you drop the hook back in, make sure it also drops into the hole of that little piece that moves the bobbin latch opener. If you miss that part, the hook (and bobbin) will be about 1/8" too high, and the screw won't tighten reliably because the hook isn't down where it's supposed to be. It's important not to run under power till you get this sorted.

A check for this would be to turn the machine over (gently) by hand and see if the latch opener moves. If the latch opener does not move, then the hook probably isn't down inside that piece.

I don't remember exactly what mine looked like that had this problem. This machine Uwe demonstrates on looks more or less foolproof, but I've had a different machine that was quite fiddly to get all the pieces to align so the hook would drop in all the way: https://www.youtube.com/watch?v=CfkGrz3OugA&t=277

The bobbin case isn't fitted properly, that tab sticking out is supposed to fit in a notch under the needle plate to stop the case from turning.
