Important Excessive chain tension may cause
transmission damage.
13. Check the speed shift control alignment with the Power
Shift slot. If the gear shift lever does not align with the
Power Shift slot in the control panel (see inset in
Fig. 6), adjust the shift rod length as follows:
A. Disconnect the ball joint from the transmission lever
and loosen the jam nut.
B. Rotate the ball joint up or down until the gear shift
lever aligns with the Power Shift slot.
C. Install the ball joint to the transmission lever and
tighten the jam nut.
14. Connect the wire to the spark plug.
Replacing the Spark Plug
Use a Champion RJ-19LM or equivalent spark plug.
Install a new plug after every 100 operating hours.
1. Stop the engine and wait for all moving parts to stop.
2. Clean any debris from around the base of the spark
plug.
3. Disconnect the wire from the spark plug (Fig. 24).
4. Remove the spark plug.
5. Examine the spark plug and replace it if it is cracked,
fouled, dirty, or if the electrodes are worn.
Important Do not clean the electrodes because grit
could enter the cylinder and damage the engine.
6. Set the gap between the electrodes on the spark plug at
0.030 in. (0.76 mm) as shown in Figure 36.

7. Install the spark plug by hand and then torque it to
15 ft.-lb. (20.4 Nm). If you do not have a torque
wrench, tighten the plug firmly.
8. Connect the wire to the spark plug.
Emptying the Fuel Tank
1. Stop the engine and wait for all moving parts to stop.
2. Disconnect the wire from the spark plug (Fig. 24)
3. Close the fuel shutoff valve (Fig. 15).
Danger
Gasoline is highly flammable; it can ignite and
cause serious personal injury.
• Drain gasoline outdoors.
• Drain gasoline from a cold engine only.
• Wipe up any gasoline that may have spilled.
• Do not drain gasoline near any open flame or
where gasoline fumes may be ignited by a spark.
• Do not smoke a cigar, a cigarette, or a pipe when
handling gasoline.
4. Place a clean drain pan under the fuel shutoff valve.
5. Loosen the hose clamp that secures the fuel line to the
valve and slide the fuel line off the fuel shutoff valve
(Fig. 15).
6. Open the fuel shutoff valve and allow the fuel to drain
out of the fuel tank into the drain pan.
7. Install the fuel line onto the fuel shutoff valve and
secure it with a hose clamp.
8. Connect the wire to the spark plug.
9. Start the snowthrower and run the engine until it stops.
Repeat this step 2 more times to ensure that the fuel
tank and the carburetor are empty.
Storage
Warning
Gasoline fumes are highly flammable, explosive,
and dangerous if inhaled. If the product is stored
in an area with an open flame, the gasoline fumes
may ignite and cause an explosion.
Do not store the snowthrower in a house (living
area), basement, or any other area where ignition
sources may be present, such as hot water and
space heaters, clothes dryers, furnaces, and other
like appliances.
