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 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 2).

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.

Removal From Storage 
Check your engine as described in the BEFORE OPERATION 
CHECKS
 section of this manual (see page 2).

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.

TRANSPORTING
Keep the engine level when transporting to reduce the possibility of 
fuel leakage. Turn the fuel valve to the OFF position (see page 2).

Carburetor Modifications for High Altitude Operation
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 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.

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.

NOTICE

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 your servicing dealer return the 
carburetor to original factory specifications.

ENGINE WILL NOT 

START

Possible Cause

Correction

1. Check control 

positions.

Fuel valve OFF.

Move lever to ON.

Choke OFF.

Move the choke/throttle 
lever, choke rod or choke 
lever to CHOKE ON 
position unless engine is 
warm. 

Ignition switch or engine stop 
switch OFF.

Move the flywheel brake 
lever to RUN position.
(Types 2 & 6: Throttle lever 
to FAST position. Type 5
Engine stop switch to ON) 

2. Check fuel.

Out of fuel.

Refuel.

Bad fuel; engine stored 
without treating or draining 
gasoline, or refueled with bad 
gasoline.

Drain the fuel tank and 
carburetor (p. 8). Refuel 
with fresh gasoline.

3. Remove and inspect 

spark plug.

Spark plug faulty, fouled, or 
improperly gapped.

Replace the spark plug (p. 
7).

Spark plug wet with fuel 
(flooded engine).

Dry and reinstall spark 
plug. Start engine with 
choke/throttle lever in 
FAST position.
(Types 4 & 5: Choke OFF 
position.)

4. Take engine to an 

authorized Honda 
servicing dealer, or 
refer to shop manual.

Fuel filter clogged, carburetor 
malfunction, ignition 
malfunction, valves stuck, 
etc.

Replace or repair faulty 
components as necessary.

ENGINE LACKS 

POWER

Possible Cause

Correction

1. Check air filter

Filter clogged.

Clean or replace filter
(p. 6).

2. Check fuel.

Bad fuel; engine stored 
without treating or draining 
gasoline, of refueled with bad 
gasoline.

Drain the fuel tank and 
carburetor (p. 8). Refuel 
with fresh gasoline.

3. Take engine to an 

authorized Honda 
servicing dealer, or 
refer to shop manual.

Fuel filter clogged, carburetor 
malfunction, ignition 
malfunction, valves stuck, 
etc.

Replace or repair faulty 
components as necessary.
