Carburetor
The carburetor is a single barrel down draft type with a metal
screened air intake filter (cleanable).
The carburetor has two metering jets, one of which is adjustable (idle
mixture). The other fast running jet is set at the factory and will
accept no adjustment.
Any adjustment to the idle mixture jet should be done with the, engine
warmed up and no load on the generator.
Electric Choke
The
electric choke uses a 12 volt heating element which opens the
choke automatically once the engine starts and is running.
NOTE: Some hunting will be present when the generator is started
and on choke with no load on the generator.
The choke is adjusted with the engine off and at room temperature.
Adjust the choke by loosening the three cover securing screws and
rotating the cover clockwise to LEAN the choke and counterclockwise to
ENRICH the choke. The choke is initially set at the factory for an
average of 70·F room temperature.
The choke may need readjustment at engine commissioning for the
ambient temperature of the area the engine is operating in.
The choke index mark is located on the choke cover lower right inboard
side.

system servicing, prime the engine fuel system by using the engine
mounted fuel pump by depressing the control panel ON switch. To
prevent unwanted activation of the carburetor's electric choke,
unplug the 12 volt (+) lead at the electric choke during this
priming and reconnect it after priming to start the engine.
