SPARK PLUG INSPECTION
The sparkplug is a very important engine component and is easy to inspect. It should be removed and
inspected on a regular basis because heating and soot deposits will slowly deteriorate it. If the electrode
is excessively eroded or there is heavy soot or other deposits, then the sparkplug should be replaced using
a recommended type and thermal grade spare part.
Before any spark plug is installed, the separation between the electrodes should be measured using a fee-
ler gauge and adjusted according to the specifications. Electrode separation should be between appro-
ximately 0.6 and 0.7 mm.
Before actually installing the new spark plug, the washer seating surface must always be thoroughly cle-
aned to prevent any foreign bodies from entering the combustion chamber. Screw the sparkplug in smo-
othly by hand and then complete tightening it with about ¼ of a turn with the correct sparkplug spanner.
