Air Cleaner
1. The air cleaner element should be cleaned because
a clogged air cleaner can cause poor engine starting,
lack of power and shorten engine life substantially.
2. Before opening the air cleaner compartment, wipe any
dirt or foreign matter from the air cleaner body and
cover, using a moist cloth. Be careful to prevent dirt
from entering the carburetor.
3. Press the latch tab on the top of the air cleaner cover
(Figure 18), and remove the cover. Check the filter to
be sure that it is clean and in good condition.

Spark Plug
1. Make sure the engine is off and cool.
2. Disconnect the spark plug cap ( Figure 19), and remove
any dirt from around the spark plug area.

3. Remove the spark plug with 5/8-inch wrench.
4. Inspect the spark plug. Replace it if the electrodes are
worn, or if the insulator is cracked or chipped. Clean the
spark plug with a wire brush if you are going to reuse it.
5. Set the spark plug gap (Figure 20) using a suitable
gauge. The gap should be between 0.024-0.028 inch
(0.60-0.70 mm).

6. Carefully install the spark plug by hand to avoid cross
threading, then tighten.
