Thank You! I think that is better now, but we will find out 100% if I can somehow fix the "wobbling" segment! The "deadzone" is about a milimeter...
Is there any way to fix the wobbling segment?

Thank You very much!
 

Follow the left shift keylever underneath the machine.  The adjustment is a 7mm A/F bolt which holds down a plate.  If you are unsure, post a picture of the underside of the machine and I will try to help you.

O.K. I will try to help   1. Remove the carriage and check the linkage that operates the 'line-lock'.  In your video, you can see that the mechanism on the back of the carriage seems to be working properly, so the problem is either the linkeage under the carriage(check to see if the typebars lock when pressing with your finger) or maybe the plate on the top of the margin stop (two screws) needs adjustment.
2. The uneven left margin fault is called 'under-banking'.  Push the carriage to the right and hold it against the margin stop. Type a capital 'O'. Let go of the carriage and type capital 'O' again.  The OO should just be touching each other, or overlapping slightly.  If not, go to the back of the carriage, where you will find the Margin Rack (that the left and right margins slide along).  There is a screw at each end of the margin rack.  Loosen the screws and slide the rack over a little.   Tighten the screws, then check OO.  When OO overlaps, the left margin should be even.  Good luck
 

I had a late Royal portable with the same alignment issue - I named the machine ClownRiter.  I eventually found the slop in the segment and, lacking master advice, found a spring to assist the segment in staying in position. It was much better after that and only the residual uppercase/lowercase misalignment remained - the ClownRiter had it all!
