ENGINE
SEE ENGINE MANUAL

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.
