4. Spark plug service
Recommended spark plug:
BPR6ES (NGK)
W20EPR-U (DENSO)
To ensure proper engine operation, the spark plug must be properly gapped
and free of deposits.
The muffler becomes very hot during operation and remains hot for a
while after stopping the engine. Be careful not to touch the muffler while it
is hot.
1. Disconnect the spark plug cap, and remove any dirt from around the spark
plug area.
2. Remove the spark plug with the proper size spark plug wrench.

3. Visually inspect the spark plug. Replace the spark plug if there is apparent
wear, or if the insulator is cracked or chipped. Clean the spark plug with a wire
brush if it is to be reused.
