BEFORE OPERATION CHECKS
IS YOUR ENGINE READY TO GO?
For your safety, and to maximize the service life of your
equipment, it is very important to take a few moments before you
operate the engine to check its condition. Be sure to take care of
any problem you find, or have your servicing dealer correct it,
before you operate the engine.
Improperly maintaining this engine, or failure to
correct a problem before operation, can cause a
malfunction in which you can be seriously hurt or
killed.
Always perform a pre-operation inspection before
each operation, and correct any problem.
Before beginning your pre-operation checks, be sure the engine is
level and the engine switch is in the OFF position.
Always check the following items before you start the engine:
Check the General Condition of the Engine
1. Look around and underneath the engine for signs of oil or
gasoline leaks.
2. Remove any excessive dirt or debris, especially around the
muffler and recoil starter.
3. Look for signs of damage.
4. Check that all shields and covers are in place, and all nuts, bolts,
and screws are tightened.
Check the Engine
1. Check the fuel level (see page 8 ). Starting with a full tank will
help to eliminate or reduce operating interruptions for refueling.
2. Check the engine oil level (see page 8 ). Running the engine
with a low oil level can cause engine damage.
3. Check the air filter element (see page 9 ). A dirty air filter
element will restrict air flow to the carburetor, reducing engine
performance.

plug and new washer, and tighten the oil drain plug securely.
Please dispose of used motor oil in a manner that is compatible
with the environment. We suggest you take used oil in a sealed
container to your local recycling center or service station for
reclamation. Do not throw it in the trash, pour it on the ground,
or pour it down a drain.
3. With the engine in a level position, fill to the upper limit mark on
the dipstick with the recommended oil (see page 8 ).
Operating the engine without an air filter, or with a damaged air
filter, will allow dirt to enter the engine, causing rapid engine wear.
This type of damage is not covered by the Distributor’s Limited
Warranty.
Inspection
Remove the air cleaner cover and inspect the filter elements.
Clean or replace dirty filter elements. Always replace damaged
filter elements.

HELPFUL TIPS & SUGGESTIONS
Draining the Fuel Tank and Carburetor
STORING YOUR ENGINE
Gasoline is highly flammable and explosive, and you
can be burned or seriously injured when handling
fuel.
Stop engine and keep heat, sparks, and flame away.
Handle fuel only outdoors.
Wipe up spills immediately.
Storage Preparation
Proper storage preparation is essential for keeping your engine
trouble-free and looking good. The following steps will help to
keep rust and corrosion from impairing your engine’s function and
appearance, and will make the engine easier to start when you use
it again.
Cleaning
If the engine has been running, allow it to cool for at least half an
hour before cleaning. Clean all exterior surfaces, touch up any
damaged paint, and coat other areas that may rust with a light film
of oil.
Using a garden hose or pressure washing equipment can force
water into the air cleaner or muffler opening. Water in the air
cleaner will soak the air filter, and water that passes through the
air filter or muffler can enter the cylinder, causing damage.
1. Place an approved gasoline container below the carburetor, and
use a funnel to avoid spilling fuel.
2. Remove the drain bolt and gasket, and drain the carburetor bowl
fuel into an approved gasoline container.
3. Move the fuel valve lever to the ON position. This will allow the
fuel tank to drain through the carburetor bowl.
Fuel
Gasoline will oxidize and deteriorate in storage. Deteriorated
gasoline will cause hard starting, and it leaves gum deposits that
clog the fuel system. If the gasoline in your engine deteriorates
during storage, you may need to have the carburetor and other
fuel system components serviced or replaced.
GASKET
The length of time that gasoline can be left in your fuel tank and
carburetor without causing functional problems will vary with
such factors as gasoline blend, your storage temperatures, and
whether the fuel tank is partially or completely filled. The air in a
partially filled fuel tank promotes fuel deterioration. Very warm
storage temperatures accelerate fuel deterioration. Fuel
deterioration problems may occur within a few months, or even
less if the gasoline was not fresh when you filled the fuel tank.

OFF
You can extend fuel storage life by adding a gasoline stabilizer
that is formulated for that purpose, or you can avoid fuel
deterioration problems by draining the fuel tank and carburetor.
4. After draining the carburetor bowl and fuel tank, move the fuel
valve lever to the OFF position.
Adding a Gasoline Stabilizer to Extend Fuel Storage Life
When adding a gasoline stabilizer, fill the fuel tank with fresh
gasoline. If only partially filled, air in the tank will promote fuel
deterioration during storage. If you keep a container of gasoline
for refueling, be sure that it contains only fresh gasoline.
5. Install the gasket and drain bolt, and tighten securely.
1. Add gasoline stabilizer following the manufacturer’s instructions.
2. After adding a gasoline stabilizer, run the engine outdoors for 10
minutes to be sure that treated gasoline has replaced the
untreated gasoline in the carburetor.
3. Stop the engine.

Engine Oil
Removal from Storage
Check your engine as described in the BEFORE OPERATION
CHECKS section of this manual (see page 3 ).
1. Change the engine oil (see page 9 ).
2. Remove the spark plug (see page 10 ).
3. Pour a tablespoon 5−10 cm (5−10 cc) of clean engine oil into
the cylinder.
If the fuel was drained during storage preparation, fill the tank with
fresh gasoline. If you keep a container of gasoline for refueling, be
sure it contains only fresh gasoline. Gasoline oxidizes and
deteriorates over time, causing hard starting.
4. Pull the starter rope several times to distribute the oil in the
cylinder.
If the cylinder was coated with oil during storage preparation, the
engine will smoke briefly at startup. This is normal.
5. Reinstall the spark plug.
6. Pull the starter grip slowly to the direction of the arrow as show
below until resistance is felt. This will close the valves so
moisture cannot enter the engine cylinder. Return the starter
rope gently.
Direction to pull
Storage Precautions
If your engine will be stored with gasoline in the fuel tank and
carburetor, it is important to reduce the hazard of gasoline vapor
ignition. Select a well-ventilated storage area away from any
appliance that operates with a flame, such as a furnace, water
heater, or clothes dryer. Also avoid any area with a sparkproducing electric motor, or where power tools are operated.
If possible, avoid storage areas with high humidity, because that
promotes rust and corrosion.
Unless all fuel has been drained from the fuel tank, turn the fuel
valve lever to the OFF position to reduce the possibility of fuel
leakage.
Keep the engine level in storage. Tilting can cause fuel or oil
leakage.
With the engine and exhaust system cool, cover the engine to
keep out dust. A hot engine and exhaust system can ignite or melt
some materials. Do not use sheet plastic as a dust cover.
A nonporous cover will trap moisture around the engine,
promoting rust and corrosion.

Carburetor Modifications for High Altitude Operation
Date Purchased: ______ / ______ / ______
Remote Control Linkage
The control is provided with a hole for cable attachment. Install a
solid wire cable or wire cable as shown below. Do not use braided
wire cable.
At high altitude, the standard carburetor air-fuel mixture will be
too rich. Performance will decrease, and fuel consumption will
increase. A very rich mixture will also foul the spark plug and
cause hard starting. Operation at an altitude that differs from that
at which this engine was certified, for extended periods of time,
may increase emissions.
High altitude performance can be improved by specific
modifications to the carburetor. If you always operate your engine
at altitudes above 1,500 meters (5,000 feet), have your servicing
dealer perform this carburetor modification. This engine, when
operated at high altitude with the carburetor modifications for
high altitude use, will meet each emission standard throughout its
useful life.
REMOTE THROTTLE LINKAGE
SOLID WIRE CABLE types:
CONTROL LEVER
Even with carburetor modification, engine horsepower will
decrease about 3.5% for each 300-meter (1,000-foot) increase in
altitude. The effect of altitude on horsepower will be greater than
this if no carburetor modification is made.
CABLE CLAMP
5 × 16 mm SCREW
THROTTLE CABLE
When the carburetor has been modified for high altitude operation,
the air-fuel mixture will be too lean for low altitude use. Operation
at altitudes below 1,500 meters (5,000 feet) with a modified
carburetor may cause the engine to overheat and result in serious
engine damage. For use at low altitudes, have your servicing
dealer return the carburetor to original factory specifications.

Emission Control System Information
Source of Emissions
The combustion process produces carbon monoxide, oxides of
nitrogen, and hydrocarbons. Control of hydrocarbons and oxides
of nitrogen is very important because, under certain conditions,
they react to form photochemical smog when subjected to
sunlight. Carbon monoxide does not react in the same way, but it
is toxic.
Maintenance
Follow the maintenance schedule on page 7 . Remember that this
schedule is based on the assumption that your machine will be
used for its designed purpose. Sustained high-load or hightemperature operation, or use in unusually wet or dusty conditions,
will require more frequent service.
Honda utilizes lean carburetor settings and other systems to
reduce the emissions of carbon monoxide, oxides of nitrogen, and
hydrocarbons.
The U.S., California Clean Air Acts and Environment Canada
EPA, California and Canadian regulations require all
manufacturers to furnish written instructions describing the
operation and maintenance of emission control systems.
The following instructions and procedures must be followed in
order to keep the emissions from your Honda engine within the
emission standards.
Tampering and Altering
Tampering with or altering the emission control system may
increase emissions beyond the legal limit. Among those acts that
constitute tampering are:
Removal or alteration of any part of the intake, fuel, or exhaust
systems.
Altering or defeating the governor linkage or speed-adjusting
mechanism to cause the engine to operate outside its design
parameters.
Problems That May Affect Emissions
If you are aware of any of the following symptoms, have your
engine inspected and repaired by your servicing dealer.
Hard starting or stalling after starting.
Rough idle.
Misfiring or backfiring under load.
Afterburning (backfiring).
Black exhaust smoke or high fuel consumption.
Replacement Parts
The emission control systems on your Honda engine were
designed, built, and certified to conform with EPA, California and
Canadian emission regulations. We recommend the use of
genuine Honda parts whenever you have maintenance done.
These original-design replacement parts are manufactured to the
same standards as the original parts, so you can be confident of
their performance. The use of replacement parts that are not of the
original design and quality may impair the effectiveness of your
emission control system.
A manufacturer of an aftermarket part assumes the responsibility
that the part will not adversely affect emission performance. The
manufacturer or rebuilder of the part must certify that use of the
part will not result in a failure of the engine to comply with
emission regulations.
