280SEL W108 Injection settings.

I recently bought a W108 280SEL, (not sure of the year, but it is between a 69 and 72 of course), I really love the car but I'm finding very difficult to find any info on it especially on setting up the Mechanical Injection. The car is running well enough, but I know it can and should be better. I really just need all the specs for the engine, I know that it is the same engine as the 280SE, but still I'm finding anything on specs imposible to find. What I need are the basics, ignition timing, main fuel line pressures and how to adjust, CO levels etc.

If anyone can tell me where to find the specs on this stuff it would be great. I work at a mechanincal workshop and even our oldest dust covered books don't cover the engine in detail. Our books tell us to set the ignition timing to 8 ATDC and the engine just doesn't want to know about it....so as I said I need SPECS!! Anything would help. Even the merc guys round here seem to know jack sh!t about the workings of this old girl.

Thanks in advance to anyone who can help me out!

Thanks for that, it is certainly a start, it doesn't have any of the specs though, like the fuel pessures setting and the likes of. I'm still in need of engine specs such as correct ingition timing. How do I set the air/fuel mixture ratio and what is the correct ratio?

Any help is good help.
