Carburetor Adjustment
Never make adjustments to the carburetor. The carburetor was set at the factory to
operate efficiently under most conditions. However, if adjustments are required, see any
Briggs & Stratton Authorized Dealer for service.
NOTICE: The manufacturer of the equipment on which this engine is installed specifies
the top speed at which the engine will be operated. Do not exceed this speed.
Inspect Muffler And Spark Arrester - Figure 1
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.
•
It is a violation of California Public Resource Code, Section 4442, to use or
•
operate the engine on any forest-covered, brush-covered, or grass-covered land
unless the exhaust system is equipped with a spark arrester, as defined in
Section 4442, maintained in effective working order. Other states or federal
jurisdictions may have similar laws. Contact the original equipment
manufacturer, retailer, or dealer to obtain a spark arrester designed for the
exhaust system installed on this engine.
8
Remove accumulated debris from muffler area and cylinder area. Inspect the muffler (I,
Figure 1) for cracks, corrosion, or other damage. Remove the spark arrester (P), if
equipped, and inspect for damage or carbon blockage. If damage is found, install
replacement parts before operating.
WARNING:
Replacement parts must be of the same design and installed
in the same position as the original parts. Other parts may not perform as well, may
damage the unit, and may result in injury.
How To Replace The Spark Plug - Figure 10
Check the gap (A, Figure 10) with a wire gauge (B). If necessary, reset the gap. Install
and tighten the spark plug to the recommended torque. For gap setting or torque, see the
Specifications section.
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.
How To Change The Oil - Figure 1
WARNING
Fuel and its vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
If you drain the oil from the top oil fill tube, the fuel tank must be empty or fuel
•
can leak out and result in a fire or explosion.
Used oil is a hazardous waste product and must be disposed of properly. Do not discard
with household waste. Check with your local authorities, service center, or dealer for safe
disposal/recycling facilities.
Remove Oil
You can drain the oil from the bottom drain hole, the side drain hole, or from the top oil fill
tube.
1. With engine off but still warm, disconnect the spark plug wire (A) and keep it away
from the spark plug (Figure 11).
2. The engine is equipped with a bottom drain (Q, Figure 1) and/or a side drain (R).
Remove the oil drain plug (H). Drain the oil into an approved container.
Note: Any of the oil drain plugs (H) shown may be installed in the engine.
3. After the oil has drained, install and tighten the oil drain plug.
4. If you drain the oil from the top oil fill tube (E), keep the spark plug end of the engine
(F) up (Figure 12). Drain the oil into an approved container.
WARNING:
If you drain the oil from the top oil fill tube, the fuel tank must
be empty or fuel can leak out and result in a fire or explosion. To empty the fuel tank,
run the engine until it stops from lack of fuel.
Add Oil
Place engine level.
•
Clean the oil fill area of any debris.
•
See the Specifications section for oil capacity.
•
1. Remove the dipstick (G) and wipe with a clean cloth (Figure 13).
2. Pour the oil slowly into the engine oil fill (H). Do not overfill. After adding oil, wait
one minute and then check the oil level.
3. Install and tighten the dipstick.
4. Remove the dipstick and check the oil level. It should be at the top of the full indicator
(J) on the dipstick.
5. Install and tighten the dipstick.
How To Service The Air Filter - Figure 15
WARNING
Fuel and its vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
Never start or run the engine with the air cleaner assembly (if equipped) or the
•
air filter (if equipped) removed.
NOTICE: Do not use pressurized air or solvents to clean the filter. Pressurized air can
damage the filter and solvents will dissolve the filter.
Two types of air filter systems are shown, a Standard and a High Capacity. Determine
the type installed on your engine and service as follows.
