Spark Plug Service<br />
In order to service the spark plug, you will need a spark plug wrench<br />
(commercially available).<br />
Recommended spark plugs:<br />
BPR5ES (NGK),<br />
W16EPR-U (DENSO)<br />
To ensure proper engine operation, the spark plug must be properly<br />
gapped and free of deposits.<br />
An incorrect spark plug can cause engine damage.<br />
If the engine has been running, let it to cool before servicing the spark<br />
plug.<br />
1. Remove the spark plug cap.<br />
2. Clean any dirt from around the spark plug base.<br />
3. Use a spark plug wrench to remove the spark plug.<br />
SPARK PLUG WRENCH<br />
SPARK PLUG CAP<br />
4. Visually inspect the spark plug.<br />
Discard it if the insulator is<br />
cracked, chipped, or fouled.<br />
5. Measure the spark plug electrode<br />
gap with a wire-type feeler gauge.<br />
Correct the gap, if necessary, by<br />
carefully bending the side<br />
electrode.<br />
The gap should be:<br />
0.0280.031 in (0.70.8 mm)<br />
0.0280.031 in<br />
(0.70.8 mm)<br />
