Proper spark plug clearance ensures the engine’s normal running.
a)
Remove the spark plug cap.
b)
Remove the spark plug using the supplied spark plug wrench.
WARNING
Be careful not to touch the muffler during or just after the engine has been running.
c)
Clean the spark plug with a steel brush. If the insulator is damaged, replace the spark
plug.
d)
Measure the spark plug clearance with a feeler. The clearance should be 0.7-0.8mm. If
adjustment is necessary, bend the side electrode carefully.
e)
Check if the spark plug gasket is in good conditions, or replace with a new one. Screw
on the spark plug to the bottom first by hand and then tighten it up by a spark plug
