4. Visually inspect the spark plug. Discard the spark plug if there is
apparent wear, or if the insulator is cracked or chipped.
Clean the spark plug with a wire brush if it is to be reused.
5. Measure the plug gap with a feeler gauge. Correct as necessary by
bending the side electrode.
The gap should be:
0.6–0.7 mm
SIDE ELECTRODE
SEALING WASHER
6. Check that the sealing washer is in good condition, and thread the
spark plug in by hand to prevent cross-threading.
