Motor runs great but smokes is it too rich?If so what can I do to cut the smoking ?If I need to lean it what is the proper setting?Can I find the mixture screw and turn it in or out to lean it?If so how much do I turn it 1/4 at a time or 1/2 turn at a time or ????? I do not want to lean it too much....Any help would be appreciated thanks

Idle mixture screw change the fuel/air ratio, NOT the fuel/oil ratio.

Best thing you can do to reduce the smoke is using a good quality oil (Mercury or Quicksilver).

BTW, The initial adjustment for the idle mixture screw, wich are located on the top port side of each carb, is lightly seated then back out 1 1/2 turn. Clockwise lean the mixture and counterclockwise enrichened it.
