SPARK PLUG MAINTENANCE
See Figure 14.
The spark plug must be properly gapped and free of deposits
in order to ensure proper engine operation. To check:
 Remove the spark plug cover.
 Remove the spark plug cap.
 Clean any dirt from around base of spark plug.
 Remove spark plug using spark plug wrench.
 Inspect spark plug for damage, and clean with a wire
brush before reinstalling. If insulator is cracked or chipped,
spark plug should be replaced. For replacement spark
plug, see Product Specifications earlier in this manual
or the accompanying engine manual, if applicable.
 Measure plug gap. The correct gap is 0.024−0.028 in.
(0.60-0.70 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.
NOTICE:
Be careful not to cross-thread the spark plug. Cross-
threading will seriously damage the product.
 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.
