This OEM Adly pilot jet is an idle jet used in the carburetor, as shown in the Carburetor section of the OEM Adly diagram.
Its function is to:
regulate fuel flow at idle
control the mixture during very small throttle openings
ensure a smooth transition between idle and the initial throttle opening
The pilot jet directly influences:
ease of starting
idle stability
low-end engine response
Its calibration is independent of the main jet, but just as critical.
