The number of the pilot jet indicates the size of the hole (highest is the largest/richest).
Too rich a mixture will give a lumpy idle (popping exhaust note), too lean a mixture will cause bogging on quick throttle openings and a zingy sound (like a smaller cc bike) when running.
The air screw can be used to perfect the mixture setting, if the air screw is less than half a turn out from full in, usually a larger jet is required and if the air screw is more than one and a half turns out from full in a size smaller jet is required.
