Hi, I have a 1970 W200 4x4 that runs quite a bit better (smoother) when
there is moisture in the air. Is there anything I can do in the way of
tuning to make it run as if it is humid all of the time? Oh, by the way, it
has a rebuilt 318 in it with a stock (small) carb. I'm not looking for any
fancy mods, just better operation.

Back off the timing a little bit.

Cars that run better when it's humid are lean. Figure out how to richen it
up a bit.

One other fact..... the higher the humidity (water) that is aspirated,
the higher the compression in the cylinder. Water doesnt compress which
escentially will give higher compression.
