CARBURETOR
Your carburetor is not adjustable. Engine performance
should not be affected at altitudes up to 2,134 meters. If
your engine does not operate properly due to suspected
carburetor problems, take your snow thrower to a service
center/department.
ENGINE SPEED
Never tamper with the engine governor, which is factory set
for proper engine speed. Overspeeding the engine above
the factory high speed setting can be dangerous and will
void the warranty. If you think the engine-governed high
speed needs adjusting, contact a service center/depart-
ment, which has the proper equipment and experience to
make any necessary ad just ments.
