240D pneumatic IP adjustment

does anyone have instructions or a diagram on how to adjust my IP?
the car NEVER smokes, not even on hard acceleration.
I think there is a little room for more fuel in my case.

There are two Full-Load Stop Screws. One on the Control Valve, a.k.a. throttle body (Fig. 00-43/3, #1), and the other on the body of the IP under the governor housing (Fig. 00-43/4, #23). Turning either of these out (CCW) will result in more fuel.

I'm seeing Section D as the starting point. If the car does not reach the set speed points for 2nd and 3rd gears, then start with making the adjustment to the full-load stop screw on the Control Valve (#1). Then go to Section F if needed.

the thing I'm trying to get is more off idle acceleration. there's a good second or two from when I mash the pedal to when the car decides to move.
