How to Replace the Spark Plug
Check the gap (A) with a wire gauge (B). If necessary, reset the gap. Install and tighten the spark plug to the
recommended torque. For gap setting or torque, see the Specifications section.
Note: In some areas, local law requires using a resistor spark plug to suppress ignition signals. If this engine was
originally equipped with a resistor spark plug, use the same type for replacement.
Inspect Muffler and Spark Arrester

extremely hot.
Severe thermal burns can occur on contact.
Combustible debris, such as leaves, grass, brush, etc. can catch fire.
.Allow muffler, engine cylinder and fins to cool before touching.
· Remove accumulated debris from muffler area and cylinder area.
WARNING:
Replacement parts must be the same and installed in the same position as the original parts or
fire could result.
