SPARK PLUG CHECK
The spark plug is an important part of the motor and it is easy to check. Take the spark plug out and
check it periodically, the high combustion temperatures and carbon deposits may effect the efficiency of
the engine. If the electrode is too eroded or carbon deposits are excessive, change the spark plug.
The correct plug is a NGK BR 9 ES
Before fitting a new spark plug, check the gap between electrodes. This gap must be between 0,6-
0,7mm.
When installing the spark plug, always clean the area, around the plug hole to prevent any dirt etc.
from entering the combustion chamber. Screw the spark plug in by hand, trying to make sure that it is
not cross threaded finally tighten it
