CHECKING THE SPARK PLUG
If engine is low on power, difficult to start or runs poorly at
idling speed, check the spark plug.
•
Allow engine to cool down. Remove spark plug.
• Clean dirty spark plug or replace with new spark plug.
• Check electrode gap (see Fig 27).
• Rectify faults which have caused fouling of spark
plug. Possible faults include:
– Too much oil or wrong type of oil in fuel tank in
two stroke engine.
– Dirty air filter or fuel filter.
– Unfavourable running conditions (e.g. operating
at part load).
– Wrong oil infrequent changes or oil usage in four
stroke engine.
Do not clean the spark plug in an abrasive grit spark plug
cleaner, as expensive damage to the engine could occur
through loose grit damaging chrome in cylinder bore.
Fit a new spark plug after approximately 50 operating hours
or earlier if electrodes are badly eroded.
Recommended spark plug is a NGK 8PMR7A, or equivalent.
Specified electrode gap is: .20”, 15mm.
