Pilot jet adjustment
The richness of air-fuel mixture with the throttle
fully closed to 1/2 open can be set by turning
the pilot jet 1. It is changed when adjustment
cannot be made by the pilot air screw alone.
A larger size jet results in a richer mixture at
low speeds, and a smaller size in a leaner mix-
ture.

Jet needle adjustment
The richness of air-fuel mixture with 1/4 ~ 3/4
throttle can be set by changing the jet needle

mixture at middle speeds, and a larger diame-
ter in a leaner mixture.
