Hey Scotch. what's your procedure? Without a specific torque figure, I just (crucially) slipped back the O-ring on my manual tensioner and turned in the screw until it was a "firm finger" tight. Without taking the O-ring out of the scenario, there is no possibility of doing it by feel.

I left the original spring in my CCT.  Just added the "back-up" bolt and a locking nut. 
Engine idling at 1000,  I back-off the locking nut, and "feel" for the sprocket and chain meshing. Too loose and I can feel the tensioner "spanking" the end of the adjusting bolt. I adjust so I can't feel that.
 The OEM spring creates the contact pressure.  The bolt and nut ensures the "guts" can't back-off.  I've still got teeth on my Nylon sprocket at 91,000K.  Also have a LISKA gear, when it's time !
You accomplish nothing by running the CCT tight.......other then wearing-out your nylon gear, faster.  Adjust the bolt with fingers, only.
