The screws on the stock carbs are AIR screws. Turning them in RICHENS mixture, backing them out adds air LEANING mixture. I think they are mostly for idle mixture.

Re: Lean issue on number 3 and 2 cylinders

follow all the oil lines back to the pump where they originate. see if any are wet with oil. This problem will most likely turn out being an oil line or carb issue. I can almost guarantee it.
