904 throttle pressure questions

Kimmer, when you say stub are you talking about the half moon of the shaft that the linkage arm goes down over and lo icks in place? If so yes and again the kick down lever is on and is in the forward position. Yes the first 1/3 of the movement is free but then you can feel it spring load as it goes back the remainder of the way. Again my question is how much pressure will moving it back create and will it do damage if it is all the way back? Once its adjusted that's where it will stay unless I would manually change it. I will be adding some type of adjusted to it this evening and trying to raise the pressure. Is there a certain pressure I should shoot for? Again it's at 90-95 psi now but arm is all the way forward.
Thanks Rod
