Re: [MBZ] 220D Questions/answers

Not a chance, the W115 220/240 has a vacuum governor and NO altitude 
adjustment -- the 300D W115 does, but not the W123s -- they have and 
anaeroid.

Adjust the smoke with the max speed screw on the "throttle" flap in the 
intake, or the max delivery screw on the back of the IP -- you should 
have just visible traces at full throttle in 3rd gear at 55 mph.

I'd also check the timing chain -- a worn chain will cause hard starts 
and excessive smoke.
