3. INSPECTING THE SPARK PLUG
(See Fig. - )
(1) Clean off carbon deposits on the spark plug electrode using a plug cleaner or wire brush.
(2) Check electrode gap. The gap should be 0.6 mm to 0.7 mm (0.02 inch.-0.03 inch.).
Adjust the gap, if necessary, by carefully bending the side electrode.
Recommended Spark Plug:
E6RC (TORCH) or BR-6HS (NGK)
