Fitting the wrong spark plug type can
damage the engine.
1. Remove the ignition cable shoe and clean
around the spark plug.
2. Remove the spark plug with a 5/8" (16 mm)
spark plug socket wrench.

the electrodes are burned or if the insulation is
cracked or damaged. Clean the spark plug with
a steel brush if it is to be reused.

IMPORTANT INFORMATION
Inadequately tightened spark plugs can
cause overheating and damage the engine.
Tightening the spark plug too much can
damage the threads in the cylinder head.
