SERVICE AND ADJUSTMENTS

NOTE:

 To seal punctures or prevent flat tires due to slow 

leaks, tire sealant may be purchased from your local parts 

dealer. Tire sealant also prevents tire dry rot and cor ro sion.

ENGINE

See engine manual.

CARBURETOR

Your carburetor is not adjustable. Engine performance 

should not be affected at altitudes up to 7,000 feet (2,134 

meters). If your engine does not operate properly due to 

suspected carburetor problems, take your snow thrower 

to a qualified service center.

TO REMOVE WHEELS (See Fig. 21)

•  Remove the klik pin and remove wheel from axle.

IMPORTANT:

 When installing wheel, be sure to use the in-

nermost hole in axle and the wheel hub hole.  To dis en gage 

drive system from the wheels (for pushing or trans port ing 

the snow thrower), remove klik pin from wheel hub and 

insert pin into the outermost hole in axle only.

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 qualified service center, 

which has proper equipment and experience to make any 

necessary ad just ments.
