[. . . ] Replace the spark plug if, upon inspection, the electrode (A, Figure 5) is burned or worn. Check the gap with a wire gauge (B) and reset, if necessary, to 0. 030 in (0. 76 mm). 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. Daily or before every use, clean the engine of any accumulated dirt or debris from the finger guard (A, Figure 10), linkage, springs, controls (B) and around and behind the muffler (C). CAUTION Do not use water to clean the engine. Over time, debris can accumulate in the cylinder cooling fins and cause the engine to overheat. This debris cannot be observed without partial disassembly of the engine. See any authorized Briggs & Stratton dealer for service assistance in cleaning the air cooling system. If gasoline in the engine has not been treated with a fuel stabilizer, it must be drained into an approved container. The use of a fuel stabilizer in the storage container is recommended to maintain freshness.

Replace the spark plug and slowly pull the starter rope to distribute the oil. Do not store in the same area as a stove, furnace, water heater, or other appliance that uses a pilot light or has a device that can create a spark. How To Clean The Air Cooling System Dirt or debris can restrict air flow and cause the engine to over heat, resulting in poor performance and reduced engine life. Storage (over 30 days) WARNING Gasoline and its vapors are extremely flammable and explosive. When Storing Gasoline Or Equipment With Fuel In Tank · Store away from furnaces, stoves, water heaters or other appliances that have pilot lights or other ignition sources because they can ignite gasoline vapors. Stale fuel causes acid and gum deposits to form in the fuel system or on essential carburetor parts. to keep fuel fresh, use Briggs & Stratton FRESH START® fuel stabilizer, available as a liquid additive or a drip concentrate cartridge. There is no need to drain gasoline from the engine if a fuel stabilizer is added according to instructions. run the engine Specifications Engine Specifications Model Displacement Bore Stroke Oil Capacity Tune-up Specifications * Model Spark Plug Gap Armature Air Gap Intake Valve Clearance Exhaust Valve Clearance 120000 11. 57 cu in (189. 6 cc) 2. 687 in (68. 25 mm) 2. 047 in (52 mm) 18 - 20 oz (0. 54 - 0. 59 L) The engine will operate satisfactorily at an angle up to 15°.
