What are the initial setting of these screws on my 1982 ATC70 carb? And what are they? idle speed screw? idle mixture screw? the book I have said to lightly seat the idle mixture screw, then back it out 1 3/4 turns, however, the book ID's both screws as the same screw on the carb.
in the enclosed picture, what are the screws outline in the red circle and outline in the blue square...thanks

Red = idle mixture 1 3/4 turns.

Blue = idle speed screw.

Needle clip - 4th groove.
