Cleaning Debris
Daily or before every use, clean accumulated debris
from engine. Keep linkage, spring and controls clean.
Keep area behind muffler free of any combustible
debris.
Spark Plug
Check the spark plug every 50 hours. Replace the
spark plug if upon inspection the electrode is burned or
worn. Ensure the spark plug is clean. Check the gap
with a feeler gauge and reset if necessary. Use only
Briggs & Stratton Spark Tester (part number 19368) to
check for spark.

Note: In some areas, local law requires using a resistor
spark plug to suppress ignition signals. If this engine
was originally equipped with a resistor spark plug, use
same type for replacement.

tanks, filters, etc.) must be the original parts, other-
wise fire can occur.
