brush before reinstalling. If insulator is cracked or
chipped, spark plug should be replaced. For replacement
spark plug, see Product Specifications earlier in this

bend the ground (top) electrode. To lessen gap, gently
tap ground electrode on a hard surface.

cross-threading.
NOTICE:
Be careful not to cross-thread the spark plug. Cross-
threading will seriously damage the product.

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.
