pilot screw?

[valkyalky]

please tell me where the pilot screw(s) is/are. No I am NOT going to mess with it/them

[Thunderbolt]

in a recess.  They have a "D" shape and require a special tool to turn.  They are sorta toward the outside of each carb.

They are located in the carburetors. If you look at each float chamber [bottom of carburetor]you will see a vertical part of the casting which is located toward the inside/center of the engine. In this casting is a pilot screw with 'D' shaped head..
