MAINTENANCE
 Clean any dirt from around base of spark plug.
 Remove spark plug using spark plug 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. 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 (not included) 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.
