To ensure proper engine operation, the spark plug must be properly
gapped and free of deposits.
∙Remove the spark plug cap.
WARNING If the engine has been running the muffler will be very
hot. Be careful not to touch the muffler.
∙Visually inspect the spark plug. Discard it if the insulator is cracked or
chipped.
∙Measure the plug gap with a feeler gauge. The gap should be
0.7‐0.8mm (0.028‐0.031 in). Correct as necessary by bending the side
electrode.
