Spark Plugs
4. Remove the spark plug from the cylinder head with a 5/8 inch spark
plug socket.
Both spark plugs should have the same light or medium tan color deposits
on the insulator around the electrode tip. The spark plug electrode tip and
bridge should have sharp, square edges.
If spark plugs are in good condition and are not due for replacement, you
can clean them with a non-metallic stiff bristle brush, set the gap and
reinstall them.
Replace spark plugs at the recommended intervals. Always replace spark
plugs in pairs.
