Located on back left corner of the engine,
the throttle controls the speed of the
engine. For proper operation information,
refer to the following section, “Operation.”
NOTE: The engine lubrication and
cooling systems operate best at full
throttle. Operating the engine at less
than full throttle for extended periods
can adversely affect the performance of
this system.
J, Fig. 3-4—Primer button
Located at the back upper left corner of
the engine. Pressing the primer button
pumps small amounts of gasoline into the
engine to improve cold weather starting.
Refer to the following section,
“Operation,” for proper operation
information.
K, Fig. 3-4—Recoil starter
Located on the back of the engine, the
engine recoil starter is used to pull-start
the engine. Refer to the following section,
“Operation” for proper operation
information.
L, Fig. 3-4—Choke knob
Controls the amount of gasoline in the
air/gasoline mixture that is fed into the
engine. This is known as “choking” the
engine. It is often necessary to “choke” a
cold engine when starting. Refer to the
following section, “Operation,” for proper
operation information.
M, Fig. 3-5—Skid shoes
Controls the distance between the auger
housing/scraper blade and the ground.
This distance should be adjusted to clear

The unit is equipped with handlebar
warmers that are automatically activated
when the engine is running. Allow a few
