13 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.
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.
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.
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 problems
may occur within a few months, or even less if the gasoline was
not fresh when you filled the fuel tank.
Fuel system damage or engine performance problems resulting
from neglected storage preparation are not covered under the
Distributor’s Limited Warranty.
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.
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.
Add gasoline stabilizer following the manufacturer’s instructions.
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.
Stop the engine. The spark arrester may be standard or an optional part, depending
on the engine type. In some areas, it is illegal to operate an engine
without a spark arrester. Check local laws and regulations. A spark
arrester is available from authorized Honda servicing dealers.
The spark arrester must be serviced every 100hours to keep it
functioning as designed.
If the engine has been running, the muffler will be hot. Allow it to
cool before servicing the spark arrester.
Remove the four 5 mm screws from the muffler protector and
remove the muffler protector.
Remove the 4 mm screw from the spark arrester, and remove
the spark arrester from the muffler.
Use a brush to remove carbon
deposits from the spark arrester
screen. Be careful not to damage
the screen. Replace the spark
arrester if it has breaks or holes.
Install the spark arrester, muffler protector, and exhaust
deflector in the reverse order of removal.
Start the engine outdoors, and
allowittowarmuptooperating

Move the throttle lever to its
minimum position.
Turn the throttle stop screw to
obtain the standard idle speed.

14If 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 spark-
producing electric motor, or where power tools are operated.
If possible, avoid storage areas with high humidity, because that
promotes rust and corrosion.
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. 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.
Wipe up spills immediately.
Place an approved gasoline container below the carburetor, and
use a funnel to avoid spilling fuel.
If the cylinder was coated with oil during storage preparation, the
engine will smoke briefly at startup. This is normal. 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. Check your engine as described in the
BEFORE OPERATION
CHECKS
section of this manual (see page ). If equipped with a battery for electric starter types, recharge the
battery once a month while the engine is in storage.
This will help to extend the service life of the battery. Handle fuel only outdoors.
Remove the carburetor drain bolt and gasket. Remove the
sediment cup and O-ring, then move the fuel valve lever to the
ON position.
After all the fuel has drained into the container, reinstall the
drain bolt, gasket, sediment cup and O-ring. Tighten the drain
bolt and sediment cup securely.
Change the engine oil (see page ).
Pour a tablespoon 5 10 cm
(5 10 cc) of clean engine oil into
the cylinder.
Pull the starter rope several times to distribute the oil in the
cylinder.
Reinstall the spark plug.
Pull the starter rope slowly until resistance is felt and the notch
on the starter pulley aligns with the hole at the top of the recoil
starter cover. This will close the valves so moisture cannot enter
the engine cylinder. Return the starter rope gently. Remove the spark plug (see page ). Keep the engine level when transporting to reduce the possibility
of fuel leakage. Turn the fuel valve to the OFF position (see
page ). 2. 1.

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. 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. Record the engine serial
number, type and purchase
date in the space below. You
will need this information when
ordering parts and when
making technical or warranty
inquiries.

17 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.
Honda utilizes lean carburetor settings and other systems to
reduce the emissions of carbon monoxide, oxides of nitrogen, and
hydrocarbons.
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 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.
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.
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 maintenancedone.
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.
Follow the maintenance schedule on page . Remember that this
schedule is based on the assumption that your machine will be
used for its designed purpose. Sustained high-load or high-
temperature operation, or use in unusually wet or dusty conditions,
will require more frequent service. Even with carburetor modification, engine horsepower will
decrease about 3.5% for each300-meter (1,000-foot) increase in
altitude. The effect of altitude on horsepower will be greater than
this if no carburetor modification is made.
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.
Fuel system damage or performance problems resulting from the
use of an oxygenated fuel containing more than the percentages
of oxygenates mentioned above are not covered under the
Distributor’s Limited Warranty. If you notice any undesirable operating symptoms, try another
service station or switch to another brand of gasoline.(methyl or wood alcohol) 5% by volume
You may use gasoline containing up to 5%
methanol by volume as long as it also
contains cosolvents and corrosion inhibitors
to protect the fuel system. Gasoline
containing more than 5% methanol by
volume may cause starting and/or
performance problems. It may also damage
metal, rubber, and plastic parts of your fuel
system. (methyl tertiary butyl ether) 15% by volume
You may use gasoline containing up to 15%
MTBE by volume. (ethyl or grain alcohol) 10% by volume
You may use gasoline containing up to 10%
ethanol by volume. Gasoline containing
ethanol may be marketed under the name
Gasohol. The following are the EPA approved percentages of oxygenates: Before using an oxygenated fuel, try to confirm the fuel’s contents.
Some states/provinces require this information to be posted on
the pump. If you use oxygenated fuel, be sure it is unleaded and meets the
minimum octane rating requirements. Some conventional gasolines are being blended with alcohol or an
ether compound. These gasolines are collectively referred to as
oxygenated fuels. To meet clean air standards, some areas of the
United States and Canada use oxygenated fuels to help reduce
emissions.
