Spark Plug - Craftsman 536.888110 Operation Manual

SPARK PLUG
Check the spark plug every twenty-five
(25) hours. Replace the spark plug if
the electrodes are pitted or burned or if
the porcelain is cracked.
To access the spark plug, the snow
hood must be removed. See "How To
Remove The Snow Hood" in the Ser-
vice And Adjustment section.
Make sure the spark plug is clean.
Clean the spark plug by carefully
scraping the electrodes (do not
sand blast or use a wire brush).
2. Check the spark plug gap with a
feeler gauge and reset gap to 0.30"
if necessary. See Figure 25.
3. Before installing the spark plug,
coat the threads lightly with oil for
easy removal. Tighten the spark
plug to a torque of 15 foot-pounds.
