Other KLX 140 REAR SHOCK

Trying to understand how to adjust rear shock .. small screwdriver slot just keeps turning ..... probably have turned it clockwise 30 turns , does it ever stop ? How about the outside nut ..? This is on top of shock ..... now on bottom side ? How does that work .. can't find PDF manual or service manual .......
 
Inner screw "top" rebound should stop or it's broken. Outer nut hi speed rebound same should stop, lower screw compression, should stop or it's broken.

Really wish people could just add a little more info like year.
