CARBURETOR ADJUSTMENT
Basic Jet Adjustment is performed with the generator operat-
ing.
Screw the jet slowly in until it seats, then back it out
1112 to 2 turns. This jet adjustment can be made in the 3600
rpm range to improve engine performance.
NOTE: An idle mixture jet adjusted too far off its seat can
induce a sooty exhaust discharge at engine start-up and shut-
down.
NOTE: At idle speed, oil pressure will be lower than the rating
of the oil pressure switch. Jump this switch to prevent engine
shutdown at idle speed.
Run Mixture Jet is presized at the factory and is not
adjustable.

CHOKE SOLENOID
The choke solenoid is a 12 volt DC operated unit that func-
tions to close the choke plate
in the carburetor when the ON
switch is depressed during engine start-up.
The choke solenoid de-energizes once the engine starts and
the
ON switch is released. Some unstable running may be
present when the engine starts cold
but should smooth out as
the engine reaches operating temperature.
Keep' this solenoid dry and periodically lubricate the linkage
between the solenoid and the choke lever.
