5. Spark plug service
Recommended spark plug: CMR5H (NGK)
To ensure proper engine operation, the spark plug must be properly gapped and
free of deposits.
If the engine has been running, the muffler will be very hot, be careful not to
touch the muffler.
CAUTION:
Never use a spark plug of incorrect heat range.
1. Loosen the 5 mm hex socket bolt with a hexagon wrench, then remove the top
cover.
2. Remove the spark plug cap and use the proper size spark plug wrench to
remove the spark plug.
3. Visually inspect the spark plug. Discard it if there is apparent wear or the
insulator is cracked or chipped. Clean the spark plug with a wire brush if it is to
be reused.
