TYPE 3: FIXED THROTTLE / ENGINE STOP SWITCH /
               MANUAL CHOKE

Starting A Cold Engine

1. Pull the choke rod to the 

CLOSED position.

2. Move the engine stop switch 

to the ON position.

Some engine applications 
use a remotely-mounted 
ignition switch rather than the 
engine-mounted engine stop 
switch shown here.

3. Pull the starter grip lightly until 

resistance is felt, then pull 
briskly.

NOTICE

Do not allow the starter grip to 
snap back against the engine. 
Return it gently to prevent 
damage to the starter.

4. If the choke rod was pulled to 

the CLOSED position to start 
the engine, push it to the OPEN 
position as soon as the engine 
warms up enough to run 
smoothly.

5. The engine speed is preset on this type.

Starting a Warm Engine

If the engine has run out of fuel, pull the choke rod to the CLOSED 
position after refueling. If the engine has not run out of fuel, leave the 
choke rod in the OPEN position.

1. Pull the starter grip lightly until you feel resistance, then pull briskly.

2. If the choke was pulled to the CLOSED position to start, push it to 

the OPEN position as soon as the engine starts.

Stopping The Engine

Move the engine stop switch to the OFF position.

OIL ALERT

®

 SYSTEM

The Oil Alert system is designed to prevent engine damage caused by 
an insufficient amount of oil in the crankcase. Before the oil level in the 
crankcase can fall below a safe limit, the Oil Alert system will 
automatically stop the engine [the throttle lever (ignition switch lever) 
will remain in a run position].

If the engine stops and will not restart, check the engine oil level 
(page 5) before troubleshooting in other areas.

SERVICING YOUR ENGINE   

THE IMPORTANCE OF MAINTENANCE 

Good maintenance is essential for safe, economical and trouble-free 
operation. It will also help reduce pollution.

To help you properly care for your engine, the following pages include 
a maintenance schedule, routine inspection procedures, and simple 
maintenance procedures using basic hand tools. Other service tasks 
that are more difficult, or require special tools, are best handled by 
professionals and are normally performed by a Honda technician or 
other qualified mechanic.

The maintenance schedule applies to normal operating conditions. If 
you operate your engine under severe conditions, such as sustained 
high-load or high-temperature operation, or use in unusually wet or 
dusty conditions, consult your servicing dealer for recommendations 
applicable to your individual needs and use.

Maintenance, replacement, or repair of the emission control 
devices and systems may be performed by any engine repair 
establishment or individual, using parts that are “certified” to 
EPA standards.

MAINTENANCE SAFETY 

Some of the most important safety precautions follow. However, we 
cannot warn you of every conceivable hazard that can arise in 
performing maintenance. Only you can decide whether or not you 
should perform a given task.

SAFETY PRECAUTIONS

• Make sure the engine is off before you begin any maintenance or 

repairs. This will eliminate several potential hazards:

Carbon monoxide poisoning from engine exhaust

.

Be sure there is adequate ventilation whenever you operate 
the engine.

Burns from hot parts

.

Let the engine and exhaust system cool before touching.

Injury from moving parts

.

Do not run the engine unless instructed to do so.

• Read the instructions before you begin, and make sure you have 

the tools and skills required.

• To reduce the possibility of fire or explosion, be careful when 

working around gasoline. Use only a nonflammable solvent, not 
gasoline, to clean parts. Keep cigarettes, sparks and flames away 
from all fuel related parts.

Remember that an authorized Honda servicing dealer knows your 
engine best and is fully equipped to maintain and repair it.
To ensure the best quality and reliability, use only new genuine Honda 
parts or their equivalents for repair and replacement.
