Remove and clean or replace the spark plug.
■■Adjust the spark plug electrode gap to 0.024 inch (0.6 mm). If the spark plug must be replaced, use only an NGK CMR5H or equivalent resistor type spark plug of the correct heat range.
CAUTION!
Before removing the spark plug, clean the area around the plug to prevent dirt and debris from getting into the engine’s internal parts.
NOTE:
The NGK CMR5H also meets the requirements for electro magnetic com- pliance (EMC).
