Spark Plug Service - Honda HHB25 Owner's Manual

Spark plug service

Recommended spark plug: CMR5H (NGK)
To ensure proper engine operation, the spark plug must be properly
gapped and free of deposits.
If the engine has been running, the spark plug and muffler
are very hot. Be careful not to touch the spark plug and muffler.
CAUTION: Never use a spark plug of incorrect heat range.
<Cleaning>
1. Pull up the smaller tab and turn up
the spark plug maintenance cover.
2. Remove the spark plug cap and
use the proper size spark plug
wrench to remove the spark plug.
3. Visually inspect the spark plug.
Discard it if there is apparent wear
or the insulator is cracked or
chipped. Clean the spark plug with
a wire brush if it is to be reused.
