SPARK ARRESTOR SCREEN
MAINTENANCE AND CARE
• SPARK PLUG
Do not attempt to remove the plug from a hot
engine in order to avoid possible damage to the
threads.
Clean or replace the plug if fouled with heavy or
oily deposits. Replace the plug if the center elec-
trode is worn rounded at the end. Spark gap 0.6-07
mm (.023"-.028") Fastening torque= 145-155kg.cm
(125-135 in. lb)
• MAGNETO
The unit incorporates an electronic ignition system,
which does not require any adjustment.
• MUFFLER AND EXHAUST PORT
In the event that the engine should lose power and
overheat, the muffler should be removed and
checked for excessive carbon deposits. Carbon
build up in the exhaust port should be removed
with a piece of wood, making sure that particles of
carbon are not allowed to enter the cylinder.
Remove all carbon deposits from the muffler flange
area and wash the complete unit in a suitable sol-
vent. Make sure the spark arrestor screen is clean.
This should be checked periodically.
