Check or Replace 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 (NGK CPR6EA-9 or equivalent) at the recommended
intervals. Always replace spark plugs in pairs.
5. Set the electrode gap with a spark plug gauge.
Gap: 0.032 inch (0.8 mm)
6. Clean the mating surface on the cylinder head and install the spark plug with a spark plug socket.
Torque: 8 ft-lbs (11 Nm)
