SPARK PLUG REPLACEMENT
Remove the spark plug cap, and then remove the spark
plug using a spark plug wrench (page 3-6).
Verify the new spark plug gap is correct (page 3-6).
Install a new spark plug finger-tight to seat the washer,
and then tighten 1/2 turn with a spark plug wrench.
A loose spark plug can become very hot and can
damage the engine. Overtightening can damage the
threads in the cylinder block.
Install the spark plug cap securely.
SPARK ARRESTER CLEANING
Remove the flange bolts (1) and muffler protector (2)
(side mount type only).
Remove the tapping screw/s (3) and spark arrester (4).
If the engine has been running, the engine will be
very hot.
Allow it to cool before proceeding.
SPARK PLUG: ZFR5F (NGK)
