REPLACING THE SPARK PLUG
Use a Champion RC14YC spark plug or equivalent.
The correct air gap is 0.76mm (0.030 in.). Replace
the plug every 100 hours of operation or once each
year, whichever comes first. This will help the engine
to start easier and run better.
1. Stop the engine and pull the spark plug wire off
of the spark plug.
2. Clean around the spark plug and remove it from
the cylinder head.
3. Set the spark plug gap (Figure 8) to 0.76mm
(0.030 in.). Install a correctly gapped spark plug
into the cylinder head.

CLEANING THE SPARK ARRESTOR SCREEN
The engine exhaust muffler has a spark arrestor
screen. Inspect and clean the screen every 100
hours of operation or once each year, whichever
comes first.
NOTE:
If using the engine on any forest-covered,
brush-covered or grass-covered unimproved
land, it must have a spark arrestor. The spark
arrestor must be maintained in good condition
by the owner/operator.
Clean and inspect the spark arrestor screen as fol-
lows:
Inspect the screen and replace if it is torn, perforated
or otherwise damaged (see Steps 1-4 below). DO NOT
USE a defective screen. If the screen is not damaged,
clean it with a commercial solvent.
If the spark arrestor is found to be damaged or defec-
tive, replace it as follows:
1. Remove the four (4) screws that connect the heat
shield to the muffler (Figure 9).
2. Remove the four (4) screws that attach the spark
arrestor screen (Figure 9).
3. Replace damaged screen with new screen
(Part No. 083083).
4. Reattach the screen and the heat shield with the
four (4) screws. Reinstall the heat shield to the
muffler with the four (4) screws.
