Volks Folks,
 
I have the AFM from my Digijet 85 GL in = front of me. I am interested in seeing if I can get my idle 02 voltage more in = the .5 volt range. My bypass screw is backed out all the way and I still have = .7 volts, so I wanted to tighten the AFM spring a little.
 
Do I move it a notch on the big black = wheel with the '"013" written on it and the notches all around the = perimeter?
 
Or do I move the small philips screw = with the silicon on it in the middle of the wiper assembly?
 
 
Appreciate any help,
