The throttle stop screw looks like it should adjust idle speed but its purpose is to keep the throttle plate off the walls of the bore. The screw should be backed off til it doesn't touch the throttle arm then be adjusted up to the arm till it just moves it.

Thanks Steve,
Did not take the picture at idle.
The screw is touching the throttle arm and is used at idle. Adjustment is very sensitive.
This is what I am interested in to do it properly (I should have said it more explicitely). Would you know how to do it at idle?
Could not find how Bosch does it the factory.
The position on the picture is full gas.
will post one picture later.
