SPARK PLUG
Neglecting the spark plug maintenance eventually leads to difficult starting and poor
performance. If the spark plug is used for a long time, the electrode gradually burns away and
carbon builds up along the inside part. In accordance with the periodic table, the plug should be
removed for inspection, cleaning and to reset the gap.
Carbon deposits on the spark plug will prevent good sparking and
cause misfiring. Clean the carbon deposits
periodically.
CARBON DEPOSIT
Check to see the carbon deposit on the Spark Plug.
If the carbon is deposited, remove it with a spark
plug cleaner machine or carefully using a tool with a
pointed end.
Check to see the worn out or burnt condition of the
electrodes. If it is extremely worn or burnt, replace
the plug and also replace the plug if it has a broken insulator,
damaged thread etc.
Thickness gauge
Spark plug gap0.6~0.7 mm (0.024-0.028 inch)
Check the spark plug for burnt condition. If abnormal replace the
Tighten the spark plug to the specified torque.
Spark plug
Tightening torque: 15-18N.m
NOTE:
To check the spark plug, first make sure that the fuel used is
unleaded gasoline.
Confirm the Specification, thread size and reach while
replacing the spark plug.
