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.
