Okay gang, some background info:

255k in the 300sel, all rubber has been replaced (vac lines and such). New injectors. New filter, new pump check valve (still on old fuel pump). New O2.

Car still is somewhat difficult to start, cold and hot (cranks more than it should). Tho' hot is easier. Has Bosch cap/rotor/plugs (non resistor)/wires. So that is good. I do have a new cold start injector coming



Recently per the site I have adjusted the fuel distributor at idle and now get a running, hot fluctuation of 41-48%. Before is was 33-37%, so I believe I am closer to what it should be at... people tend to recommend 40-50%. Is a certain percentage preferred over another?

Now one question I have, which direction richens up the fuel mixture? And would this be a higher percentage?

I did turn the EHA half a turn when I first bought the car (why, I can't recall). Would this be corrected for at the fuel distributor's base fuel mixture tower?
