5.7 Carburetor Adjustment
See Graphic: wc_gr000032
5.7.1 Start the engine and allow it to warm up to operating temperature.
5.7.2 Set the pilot screw (a) two turns out. See Note.
5.7.3 With the engine idling, turn the pilot screw (a) in or out to the setting
that produces the highest rpm.
5.7.4 After the pilot screw is adjusted, turn the throttle stop screw (b) to
obtain the standard idle speed. See Technical Data.
Note: On some engines the pilot screw is fitted with a limiter cap (c)
to prevent excessive enrichment of the air-fuel mixture in order to
comply with emission regulations. The mixture is set at the factory and
no adjustment should be necessary. Do not attempt to remove the
limiter cap. The limiter cap cannot be removed without breaking the
pilot screw.
5.8 Cleaning Sediment Cup
See Graphic: wc_gr000029
5.8.1 Turn the fuel valve off.
5.8.2 Remove the sediment cup (a) and the O-ring (b).
5.8.3 Wash both thoroughly in a nonflammable solvent. Dry and reinstall
them.
5.8.4 Turn the fuel valve on and check for leaks.
