Thank you Bob - incidentally my main concern was the  black smoke coming out 
of the exhaust at idle, namely:

rich at idle 

A) Increase  initial timing
B) Go in on mixture screws
C) Readjust butterfly  positions
D) Lower float level
E) Decrease fuel pressure
 
 
currently the timing on my 140 hp is set at 16 degrees  - I'm gonna try 
advancing it a few more degrees :)

Tony,
Black smoke at idle indicates a very rich mixture. The above possible  
causes/corrections are very general in nature. I suggest you first  determine which 
carb (or both0 is the problem. Then look to see if gas is  dripping or 
dribbling from the cluster at an idle.That is the likely  cause.
