Fuel adjustment on a non-turbo '84 300D
 

Does anyone have the procedure for adjusting the Injector Pump fuel delivery on a non-turbo '84 300D? (in Oz - not many Turbos on W123 300D's here).
I would like to see if I can get a little more power out of it.
I presume it would be similar to the procedure for the 240D.

Anyone?

I think you may be able to fiddle with the ADA (altitude compensator) on top, and if not, you have to open the back of the pump (governor cover plate) and turn up the full-load fuel adjusting screw. I've never done this but plan to try on my turbo engine. Here's the PDF for the OM603 turbo pump, I have NO idea what yours looks like though - I'm sure it's not the same:
