Onan P216 - Carburetor Replacement; Carburetor High-Altitude Jet (Optional)

I CARBURETOR (BEGINNING SPEC G)
Carburetor Replacement
(fixed-type) with the optional high-altitude jet (Fig-
ure 4a), fuel mixture adjustments should not be at-
tempted. Nor should the carburetor be overhauled.
instead, a malfunctioning carburetor should be re-
placed. Before replacing a carburetor, however,
make certain
1) that all other necessary engine and
generator adjustments and repairs have been per-
formed and
2) that the carburetor is actually mal-
functioning (see
Engine Troubleshooting).
To remove the carburetor, remove the air cleaner,
disconnect the fuel line and choke and throttle link-
ages and unbolt the carburetor from the intake man-
ifold. When mounting the carburetor always use a
new gasket. Readjust the choke and throttle cables
and engine speed as instructed in the engine or
equipment Operator’s Manual.
Carburetor Hig h-Altitude Jet (Optional)
If the engine is operated at an altitude above 5,000
feet (1,524 metres), it is recommended that the car-
buretor main fuel jet
be replaced with the optional
high-altitude jet (which has a slightly smaller ori-
fice).
-1 To avoid sripping and gouging the
main fueljet,
use a screwdriver with a 5/16 inch
(8 mm) wide blade.
