Hello,
i have an old Bosch service manual from 1966 for adjusting the fuel injection Pump R11 for a 230SL. If somebody is interested in reading it,i can post it. It is a tif file. And it is written in german.
But be aware of the fact, that you can not adjust a pump without a testing equipement (Pumpenprüfstand). You can only adjust some things like the cold start gadget. And you can see on some pictures how it works.
However, may be somebody is interested in it.
Best regards Franz
