SPARK PLUG MAINTENANCE
See Figure 16.
The spark plug must be properly gapped and free of deposits
in order to ensure proper engine operation. To check:
Remove the spark plug cap.
Clean any dirt from around base of spark plug.
Remove spark plug using wrench (not included).
Inspect spark plug for damage, and clean with a wire
brush before reinstalling. If insulator is cracked or
chipped, spark plug should be replaced.
NOTE: If replacing, use the following recommended
spark plugs or equivalent: NGK BR-6HS or Champion
RL86C.

(0.7-0.8 mm). To widen gap, if necessary, carefully bend
the ground (top) electrode. To lessen gap, gently tap
ground electrode on a hard surface.
Seat spark plug in position; thread in by hand to prevent
cross-threading.
Tighten with wrench to compress washer. If spark plug
is new, use 1/2 turn to compress washer appropriate
amount. If reusing old spark plug, use 1/8 to 1/4 turn for
proper washer compression.
NOTE: An improperly tightened spark plug will become
very hot and could damage the engine.
CLEANING THE EXHAUST PORT AND
MUFFLER
Depending on the type of fuel used, the type and amount of
lubricant used, and/or your operating conditions, the exhaust
port and muffler may become blocked with carbon deposits.
If you notice a power loss with your gas-powered products,
you may need to remove these deposits to restore perfor-
mance. We highly recommend that only qualified service
technicians perform this service.
SPARK ARRESTOR
See Figure 17.
Inspect the spark arrestor for breaks or holes. Replace
if necessary. To purchase a replacement spark arrestor

Use a brush to remove carbon deposits from the spark
arrestor screen as needed.
