Why this seesaw is working against physics laws

See the link.i did some changes to prove Overunity.for calculations.

If calculate then .the length of tube is 1 meter and it's 30 cm length is mounted with arm.the rest 70 cm is upside so I will have to lift up only 30 cm with 10 kg mass.
If counter weight is 13 kg then the seesaw will be tilted already 70 degree.
The arm length is 2 meter.
Now if I lift up the 10 kg mass then toal mgh=130 Joule but minus 100 Joule of counter weight.
30 joule + 30 Joule of extra counterweight energy so total 60 Joule.
But ouput if ball fall down from 1 meter then 100 Joule and again fall down at the time of reversing then 90 Joule so total output energy will be 190 Joule but input is only 60 Joule.
Even I myself feeling the energy of falling ball in the device but at the time of booking the energy is very less.though hand is not perfect way but I think the difference can be find out by anyone falling ball and input energy.

The arm is getting twisted due to lack of perfection between nail and hole otherwise there would be clear-cut momentum in it.
I did it with 80 cm arm but if I take 2 meter arm then the center of mass can be kept equal to fulcrum.

Noether theorem will not work in this mechanism as it is stopping for a moment in each back and forth step.

E = mgh(initial) - mgh (final)

[Low-Q]

E = mgh(initial) - mgh (final)

0 - 0 to be exact.
