Spark Plug Gap Specification : 0.6 - 0.7 mm (0.024 - 0.028 in.)
Adjusting Plug Gap :
Adjust the gap by bending only the outside negative electrode. Use a Spark Plug Gap Gauge to check if the distance is correct.
Removal of Spark Plugs :
1 ) Blow any debris that has collected in the spark plug wells to prevent it them from falling into the cylinders while the plugs are removed.
2 ) Gently remove the electrical leads. Don't jerk them, as the wires may disconnect from the insulator boots.
3 ) Back out the plugs with a socket.
Inspection :
The normal color of a spark plug tip ranges from a light tan to a chocolate brown. If the old plugs are to be used again, check them for deposits on the electrodes, cracked insulators, damaged threads, or eroded electrodes. If any plug is found to be unsatisfactory, discard the set.
