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
(not included) 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. 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.
