11. Remove fixing device on top of needle by
depressing the device and turning it left.
Remove spring and needle.
12. Inspect needle for wear, air pressure piston for
damage and diaphragm for cracks and aging.
Replace as a set if necessary.
13. Remove fuel bowl, float and needle valve.
14. Inspect needle valve and valve seat for
damage and blockage.
NOTE:
If the needle valve is damaged or blocked, the
air-tightness between the valve and valve seat is
not proper, which results in float height raise and
then oil leakage. In such a case, the valve must be
replaced with a new one.
15. Remove main jet, needle valve seat, idle
metering jet and jet adjuster.
NOTE:
Make sure the jet, the nozzle seat and the adjuster
are not damaged. Note down the turns given to the
adjusting screw in removal.
