MAINTENANCE
Engine Breather Hose Inspection
The engine is equipped with a breather hose. Inspect the
breather hose for possible kinks or wear. The hose is form fit-
ted for a proper fit. Follow the breather hose from the side of
the airbox to the engine valve cover.
NOTE: Make sure line is not kinked or pinched.
Engine and Transmission Mount Locations
Periodically inspect engine and transmission mounts for cracks
or damage.
Compression and Leakdown Test
NOTE: This engine does NOT have decompression
components. Compression readings will vary in
proportion to cranking speed during the test.
A smooth idle generally indicates good compression. Low
engine compression is rarely a factor in running condition
problems above idle speed.
A cylinder leakdown test is the best indication of engine
condition. Follow manufacturer's instructions to perform a
cylinder leakage test (never use high pressure leakage testers, as
crankshaft seals may dislodge and leak).
Exhaust - Spark Arrestor
Periodically clean spark arrestor to remove accumulated carbon.
1.
Remove the retaining screw and remove the arrestor from
the end of the silencer.
2.
Use a non-synthetic brush to clean the arrestor screen. A
synthetic brush may melt if components are warm.
3.
Inspect the screen for wear and damage. Replace if needed.
4.
Reinstall the arrestor and torque the screw to
40 in. lbs.
(4.5 Nm)

WARNING
Do not clean spark arrestor immediately after the
engine has been run, as the exhaust system
becomes very hot. Serious burns could result from
contact with the exhaust components. Allow
components to cool sufficiently before proceeding.
Wear eye protection and gloves.
Never run the engine in an enclosed area. Exhaust
contains poisonous carbon monoxide gas that can
cause loss of consciousness or death in a very
short time.
