Spark Plug - Honda GC160 Owner's Manual

SPARK PLUG

Recommended Spark Plugs: NGK BPR6ES
The recommended spark plug is the correct heat range for normal
engine operating temperatures.
NOTICE
Incorrect spark plugs can cause engine damage.
For good performance, the
spark plug must be properly
gapped and free of deposits.
1. Disconnect the cap from
the spark plug, and remove
any dirt from the spark plug
area.
2. Use the proper size spark
plug wrench to remove the
spark plug.
3. Inspect the spark plug. Replace it if
damaged, badly fouled, if the sealing
washer is in poor condition, or if the
electrode is worn. If the spark plug is
to be reused, clean it with a wire
brush.
4. Measure the electrode gap with a
suitable gauge. The correct gap is
0.70 - 0.80 mm (0.028 - 0.031 in). If
adjustment is needed, correct the
gap by carefully bending the side
electrode.
0.70 ~ 0.80 mm
