Guys please tell me if I'm wrong

If you screw in the Air/Fuel Mixture Screw all the way
in while idling and the engine does not die, you should go to a
smaller pilot jet. The engine should die before it gets that far in.
Less than 1 turn out, you should go smaller also

The goal is to find the setting that provides the highest and smoothest RPM idle.
Usually between 1 - 3 turns and then your pilot jet is correct.

More than 3 Turns out then you might need a bigger pilot jet.

The typical Fuel Screw settings are in the 1 1/2 to 2 1/2 range.
