Spark Plug
Check the spark plug every 100 hours. Replace the
spark plug if upon inspection the electrodes Ê are
burned or worn. Ensure the spark plug is clean. Check
the gap Ë with a feeler gage Ì and reset to .51 mm or
0.020 in. if necessary. Use only Briggs & Stratton Spark
Tester (part number 19368) to check for spark.
Note: In some areas, local law requires using resistor
spark plug to suppress ignition signals. If this
engine was originally equipped with resistor
spark plug, use same type for replacement.
