SPARK PLUG
REMOVAL AND INSTALLATION
Note the following points:
1. When the high-tension lead is to be pulled off, be
sure to pull the boot itself, and not the wire.
2. Tighten the spark plugs to the specified torque.
Tightening torque: 15—23 N-m
(1.5—2.3 m-kg, 10.8—16.6 ft-lb)

INSPECTION
Check the following points. If a problem is found, re-
place the spark plug.
1. Damaged insulation
2. Worn electrodes
3. Carbon deposits
If cleaning is necessary, use a plug cleaner or a
wire brush. Clean the upper insulator also.
4. Damaged gasket
5. Burnt condition of spark insulator
6. If it is black with carbon deposits, either misfiring
due to improper proportions of gas and air or over-
heating of the plug may have occurred.
