Clean/replace spark plug every 100 hours or every season, whichever occurs first. Spark plug wrench is available from any Authorized Briggs & Stratton Service Dealer.

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

Spark plug gap Ì should be 0.76 mm (0.030 in).

WARNING

DO NOT attempt to start engine with spark plug removed. Fuel can ignite and cause a fire or explosion. If you need to check for spark, use only Briggs & Stratton Spark Tester, to check for spark.

WARNING

Store in a clean, dry area. DO NOT store near a stove, furnace or water heater which uses a pilot light or any device that can create a spark.

KEEPING ENGINE CLEAN

Periodically remove grass and chaff build-up from engine. Clean finger guard. Do not spray engine with water to clean because water could contaminate fuel. Clean with a brush or compressed air.

If muffler is equipped with spark arrester screen Ë, remove spark arrester screen for cleaning and inspection every 50 hours or every season. Replace if damaged. To assure smooth operation, keep governor linkage, springs and controls Ê free of debris.

Clean cooling system. Chaff or debris may clog engine’s air cooling system, especially after prolonged operation. Remove blower housing and clean as shown Î.

STORAGE

Engines stored over 30 days need to be protected or drained of fuel to prevent gum from forming in fuel system or on essential carburetor parts.

For engine protection, we recommend use of Briggs & Stratton Fuel Stabilizer.

Note: If stabilizer is not used or if engine is operating on gasoline containing alcohol, e.g. gasohol, remove all fuel from tank and run engine until it stops from lack of fuel.

1.Change oil. See Oil service.

2.Remove spark plug and pour about 15 ml (1/2 oz) of engine oil into cylinder. Replace spark plug and crank slowly to distribute oil.

3.Clean chaff and debris from cylinder and cylinder head fins, under finger guard and behind muffler.

4.When removing the unit from storage, only use fresh gasoline. Perform operation checks, see maintenance schedule, before starting engine.
