Servicing the Spark Plug

Ensure that the air gap between the center and side electrodes is correct before installing the
spark plug. Use a spark plug wrench for removing and installing the spark plugs and a gapping
tool/feeler gauge to check and adjust the air gap. Install a new spark plug if necessary.
Type: BPR6ES (NKG) or equivalent. Air Gap: 0.28-0.031 inch (0.70-0.80 mm)
Removing the Spark Plugs
1. Pull the wire off of the spark plug
2. Clean around the spark plug.
3. Remove spark plugs and metal washer

Checking the Spark Plugs

1. Look at the center of the spark plug. If you see
light brown or gray on the insulator, the engine
is operating properly. A black coating on the
insulator usually means the air cleaner is dirty.
Important: Never clean the spark plug. Always
replace the spark plug when it has a black
coating, worn electrodes, an oily film, or cracks.
2. Check the gap between the center and side
electrodes.
3. Bend the side electrode if the gap is not
correct.
Installing the Spark Plugs
1. Thread the spark plugs into the spark plug
hole.
2. Tighten the spark plugs to 20 ft-lb (27 N-m).
3. Push the wire onto the spark plug
