the plug once each year.
This will help the engine start easier and
run better.
1. Stop the engine and pull the spark plug wire off of the spark
plug.
2. Clean the area around the spark plug and remove it from the
cylinder head.
3. Set the spark plug's gap to 0.76 mm (0.030 in.). Install the
correctly gapped spark plug into the cylinder head and torque
to 15 ft/lbs. (Figure 13).

3.3.7 SPARK ARRESTOR
The engine exhaust muffler has a spark arrestor screen. Inspect
and clean the screen at least once each year (Figure 14). If unit is
used regularly, inspect and clean more often.

or grass-covered unimproved land, it must equipped with a
spark arrestor. The spark arrestor must be maintained in good
condition by the owner/operator.
Clean and inspect the spark arrestor as follows:
1. Remove clamp and spark arrestor from muffler.
2. Inspect screen and replace if torn, perforated or otherwise
damaged. DO NOT USE a defective screen. If screen is not
damaged, clean it with commercial solvent.
3. Replace the spark arrestor and clamp.
