Service Spark Plug
NOTICE Spark plugs have different thread lengths and
heat ranges. When changing a spark plug, use only the
specified replacement or engine damage could occur.
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 the same
type for replacement.

Disconnect the spark plug wire.
2.
Remove and inspect spark plug for wear and damage.
Replace spark plug if electrodes are burned away or if
the porcelain is cracked.
3.
Do not sand-blast or bead-blast the spark plug. Clean
by scraping or wire brushing and then washing in a
commercial solvent.

Clean Air Cooling System
WARNING
Running engines produce heat. Engine parts, especially
muffler, become extremely hot.
Severe thermal burns can occur on contact.
Combustible debris, such as leaves, grass, brush, etc.,
can catch fire.
• Allow muffler, engine cylinder and fins to cool before
touching.
• Remove accumulated debris from muffler area and
cylinder area.
NOTICE Do not use water to clean the engine. Water
could contaminate the fuel system. Use a brush or dry
cloth to clean the engine.
This is an air cooled engine. Dirt or debris can restrict air
flow and cause the engine to overheat, resulting in poor
performance and reduced engine life.
1.
Use a brush or dry cloth to remove debris from the air
intake area (A).
2.
Keep linkage, springs and controls (B) clean.
3.
Keep the area around and behind the muffler (C) free
of any combustible debris.
4.
Use a brush, vacuum and/or compressed air to remove
debris from cylinder cooling fins.
After a period of time, debris can accumulate in the cylinder
cooling fins and cause the engine to overheat. This debris
cannot be removed without partial disassembly of the
engine. Have a Briggs & Stratton Authorized Dealer inspect
