Pilot air screw adjustment
The richness of air-fuel mixture with full closed to
1/4 throttle can be set by turning the pilot air
screw

.
Turning in the pilot air screw will enrich the mix-
ture at low speeds, and turning out it will lean out
the mixture.
EC71R000
Pilot jet adjustment
The air-fuel mixture can basically be adjusted by
the pilot air screw from full closed to 1/2 throttle.
If the pilot air screw is not enough for this adjust-
ment, the pilot jet
1
is changed.
A larger size jet results in a richer mixture at low
speeds, and a smaller size in a leaner mixture.
