What does changing the pilot jet do?
Changing the main jet size will adjust the top end of the operating range from half to full throttle. Adjusting the needle jet size, jet needle, and needle clip position will affect the mid range operation. This leaves the pilot jet size and the pilot screw for the idle and low throttle conditions.
Which way is lean and rich?
When an air/fuel mixture has too much fuel, it is rich. When there is not enough fuel, it is lean. An AFR higher than stoich = lean. An AFR lower than stoich = rich.
