I went out a looked at the tune-up specs on the label pasted on my 1980 240DL ---drivers side shock tower. normal B21F

Timing with vacumm hoses off : 750 +/50 RPM 8 deg BTDC +/- 2 deg.

CO adjustment: 900+/- RPM

Idle (Normal): 950 +/- 50

"
I also note now that I can screw the idle screw all the way in and lower the idle to around 800 RPM, but can't completely kill it."

I have removed that Plastic idle screw and found its end to be pretty dirty. Just keep unscrewing. It's just a large needle valve. And I remember an O-ring too.


At least you've eliminated the CO adjustment from you list.
