2. Clean any debris from around the base of the spark
plug.
3. Disconnect the wire from the spark plug (Fig. 25).
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 37.

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
