This engine is certified to comply with U.S. EPA and California ARB
emission regulations using the Impco Beam regulator specified in the
installation instructions (see below). Honda used this regulator and
other specific parts and adjustments to demonstrate compliance with
the emission regulations. Adjustable fuel system parts must have
U.S. EPA and California ARB approved tamper resistant features to
limit the available adjustment after the fuel system is correctly
installed. If an equipment manufacturer did not install your engine in a
product you will need the installation instructions for the Honda
certified system (see below). If you choose not to use the Honda fuel
system you must use a system that has been certified by the fuel
system manufacturer to be used on this Honda engine. Or if you use
a fuel system that is not already certified you must have certification
test data satisfactory to the U.S. EPA or the California ARB. The test

Storage Preparation
4. Measure the electrode gap with a
suitable gauge. The correct gap is
0.028 - 0.031 in (0.70 - 0.80 mm). If
adjustment is needed, correct the gap
by carefully bending the side electrode.
Proper storage preparation is essential for keeping your engine
troublefree 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
5. Install the spark plug carefully, by hand,
to avoid cross-threading. After the
spark plug is seated, tighten with the
proper size spark plug wrench to compress the washer. When
installing a new spark plug, tighten 1/2 turn after the spark plug
seats to compress the washer. When reinstalling the original spark
plug, tighten 1/8 - 1/4 turn after the spark plug seats to compress
the washer.
If the engine has been running, allow it to cool for at least half an hour
before cleaning.
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. 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.
NOTICE
A loose spark plug can become very hot and can damage the
engine. Overtightening the spark plug can damage the threads in
the cylinder head.
6. Attach the spark plug cap to the spark plug.
SPARK ARRESTER (optional equipment)
In some areas, it is illegal to operate an engine without a USDA
(United States Department of Agriculture)-qualified spark arrester.
Check local laws and regulations. A USDA-qualified spark arrester is
available from an authorized Honda servicing dealer. The spark
arrester must be serviced every 100 hours 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.
Spark Arrester
Removal
1. Remove the three
5 mm screws and
remove the heat
shield.
2. Remove the 8 mm
nuts and then
remove the
identification plate,
muffler and gasket.
Fuel system damage or engine performance problems resulting from
neglected storage preparation are not covered under the Distributor’s
Limited Warranty (see page 11). 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.
LPG fuel does not require treatment during storage.

TECHNICAL & CONSUMER INFORMATION
STORAGE PRECAUTIONS
TECHNICAL INFORMATION
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 spark-producing electric motor, or
where power tools are operated. If possible, avoid storage areas with
high humidity, because that promotes rust and corrosion. If there is
gasoline in the fuel tank, leave the fuel valve in the OFF position (see
page 4). Keep the engine level during 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.
Serial Number Location
Record the engine model
identifier, engine serial
number and engine type in the
space below. You will need
this information when ordering
parts and when making
technical or warranty inquiries.

NUMBER
LOCATION
REMOVAL FROM STORAGE
SERIAL NUMBER
Check your engine as described in the BEFORE OPERATION
CHECKS section of this manual (see page 3). 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. If the cylinder was coated with oil during storage preparation,
the engine will smoke briefly at startup. This is normal.

Carburetor Modifications for High Altitude Operation
Emission Control System Information
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.
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. Honda utilizes
lean carburetor settings and other systems to reduce the emissions of
carbon monoxide, oxides of nitrogen, and hydrocarbons.
High altitude performance can be improved by specific modifications to
the carburetor. If you always operate your trimmer at altitudes above
5,000 feet (1,500 meters), 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.
The U.S. and California Clean Air Acts
EPA and California 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.
Even with carburetor modification, engine horsepower will decrease
about 3.5% for each 1,000-foot (300-meter) increase in altitude. The
effect of altitude on horsepower will be greater than this if no
carburetor modification is made
Tampering and Altering
NOTICE
Tampering with or altering the emission control system may increase
emissions beyond the legal limit. Among those acts that constitute
tampering are:
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 5,000 feet (1,500 meters) with a modified carburetor
may cause the engine to overheat and result in serious engine
damage. For use at low altitudes, have an authorized Honda servicing
dealer return the carburetor to original factory specifications.
• 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
LPG Models:
There are no high altitude adjustments for LPG models, however,
engine performance will decrease.
If you are aware of any of the following symptoms, have your engine
inspected and repaired by an authorized Honda servicing dealer.
Oxygenated Fuels
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. If you use oxygenated fuel, be sure it is unleaded and
meets the minimum octane rating requirements. Before using an
oxygenated fuel, try to confirm the fuel’s contents. Some states/
provinces require this information to be posted on the pump.
• 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 and California 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.
The following are the EPA approved percentages of oxygenates:
ETHANOL
— (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.
MTBE
— (methyl tertiary butyl ether) 15% by volume
You may use gasoline containing up to 15% MTBE
by volume.
METHANOL — (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.
Maintenance
Follow the maintenance schedule on page 4. 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.
If you notice any undesirable operating symptoms, try another service
station or switch to another brand of gasoline.
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 (see page 11).
LPG Fuels
Use LPG fuel with a propane content of 95% or higher. LPG fueled
engines are certified to operate on LPG only.
