Default Frustrating powervalve problem 2018 ec300

Ive just pulled the cover off the right hand side powervalve and removed the lever arm and pulled it off the powervalve. I then removed the small metal plate that connects the arm to the powervalve shaft so i could view the bearing.
Now I am in the process of putting it back together and I am having problems. I can see that this metal plate should spin and make contact with the small screw beside the bearing but it is not going far enough in either a clockwise or counterclockwise direction to make contact with it. It is as though the shaft has moved somehow and it just doesnt want to spin far enough for me to slip the plate back on.
Very hard for me to explain it but I hope someone knows what I am talking about. Also, the actuating rod seems to be stuck in the up position and needs a considerable amount of force to move down.. Is this normal.

It has not spun 180 degrees out has it? Take a look up the exhaust port to see the flap is not hanging too low. Regarding the power valve arm, if you pulled up on it with it disconnected you may have dislodged one of the balls which requires the inner clutch cover to be removed to rectify. Did the power valve just get cleaned?
Back on a gassy! 2018 EC300! 🤘
