3. Clean any dirt from around base of spark plug.
4. Remove spark plug (A) using provided wrench.
5. Inspect spark plug for damage, and clean with a
wire brush before reinstalling. If insulator is
cracked or chipped, spark plug should be replaced.
6. Measure plug gap. The correct gap is 0.028-0.031
in. (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.
7. Seat spark plug in position; thread in by hand to
prevent cross-threading.

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.
