Proper spark plug clearance ensures the engine’s normal running under no deposit around the
spark plug.
a) Remove the spark plug by means of spark plug wrench.
WARNING
Be careful not to touch the muffler during or just after the engine has been
running.
b) Clean the spark plug with a steel brush. If the insulator is damaged, replace the
spark plug.
c) 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.
d) 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 wrench. If a new spark plug is used, twist 1/2 more turns after impacting the
gasket; if reinstall the original one, just twist 1/8-1/4 more turns
