CHOKE (ENRICHER)
ADJUSTMENT
Boot
If the choke knob does not stay out when pulled,
adjust the choke tension by tightening (clockwise) the
jam nut under the rubber boot between the choke
knob and nut. Firmly grasp the rubber boot and
tighten until the choke slides freely but stays out when
pulled.
PILOT SCREW
The pilot system supplies fuel during engine operation
with the throttle valve closed or slightly opened. The
fuel/air mixture is metered by pilot screw and
discharged into the main bore through the pilot outlet.
CAUTION:
The pilot screw is calibrated at the factory to meet EPA / CARB
regulations for air quality standards and is sealed with a brass
plug to prevent tampering. Removal of the tamper proof plug
is not permitted. For service purposes, cleaning of the pilot
circuit can be done only by a certified repair shop to ensure air
quality standards are not exceeded.
