Spark Plug

DO NOT check for a spark with the spark plug removed. DO NOT
crank the engine with the spark plug removed.
If the engine has been running, the muffler will be very hot. Be careful
not to touch the muffler.
The spark plug should be checked every 25 hours and changed once
a season or every 100 hours. To ensure proper engine operation, the
spark plug must also be properly gapped and free of deposits.
1. Remove the spark plug boot and use a spark plug wrench to
remove the plug, Figure 18.
2. Visually inspect the spark plug. Discard the spark plug if there is
any apparent wear, or if the insulator is cracked or chipped. Clean
the spark plug with a wire brush if it is to be reused.
NOTE: A resistor spark plug must be used for replacement. Contact
a Sears Parts and Repair Center for a replacement spark plug (Part #
951-10292).
