1. When I push clutch handle I can turn 1st gear on or go back to neutral but I would expect that with 1st gear on and handle fully pushed the wheel stays still. In fact it is rotating no matter I use clutch handle or not.
Earlier I detached the push lever like this

Now it is easy to pull or put it on again. Thourgh a hole I can see this thing a liitle bit

It is very easy to turn this lever clockwise or counter. I would expect some tension.
2. Handle goes back poorly. I guess the cable is old and dirty, but this spring attached to clutch cover doesn't give much power. Doesn't anything inside the clutch should tense back additionaly?
Thanks in advace for any feedback.
