Yes, that IS the one I am talking about, but it has nothing to do with tension on the throttle shaft. It's an idle stop screw, just like on a carburetor and only controls the opening of the throttle blades when the gas pedal is released.
jas 88 I think we are saying the same thing. Yes it only works when the blades are closed (idle). When I was taking mine apart I watched what it did and yes it does open and close the blade a small amount. If it is moving the blades it has to be connected to the shaft that the blades screw into. If that is not the throttle shaft that holds the blades I am not sure what it is called. I can assure you when I closed the screw completely those blades will not move on mine. Loosen the screw just a little and it will drag the blades which could cause them to stick when you gas it. So I think the reason they don't want you adjusting it is because it could stick and cause a wide open situation when you release the pedal.
I am only going on observation not knowledge. Sandy

What he said. All it does is stop the butterflies from closing further through the linkage. It is not connected to the throttle shaft.
