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.
