A FEW WORDS ABOUT SAFETY SERVICE INFORMATION The service and repair information contained in this manual is intended for use by qualified, professional technicians. Attempting service or repairs without the proper training, tools, and equipment could cause injury to you or others. It could also damage the engine or create an unsafe condition. This manual describes the proper methods and procedures for performing service, maintenance, and repairs. Some procedures require the use of special tools. Any person who intends to use a replacement part, service procedure, or a tool that is not recommended by Honda, must determine the risks to their personal safety and the safe operation of the engine. If you need to replace a part, use genuine Honda parts with the correct part number, or an equivalent part. We strongly recommend that you do not use replacement parts of inferior quality. For Your Customer’s Safety Proper service and maintenance are essential to the customer’s safety and the reliability of the engine. Any error or oversight while servicing an engine can result in faulty operation, damage to the engine, or injury to others. For Your Safety Because this manual is intended for the professional service technician, we do not provide warnings about many basic shop safety practices (eg, Hot parts – wear gloves). If you have not received shop safety training or do not feel confident about your knowledge of safe servicing practices, we recommend that you do not attempt to perform the procedures described in this manual. Some of the most important general service safety precautions are given below. However, we cannot warn you of every conceivable hazard that can arise in performing service and repair procedures. Only you can decide whether or not you should perform a given task. Important Safety Precautions Make sure you have a clear understanding of all basic shop safety practices and that you are wearing appropriate clothing and using safety equipment. When performing any service task, be especially careful of the following: Read all of the instructions before you begin, and make sure you have the tools, the replacement or repair parts, and the skills required to perform the tasks safely and completely. Protect your eyes by using proper safety glasses, goggles, or face shields any time you hammer, drill, grind, or work around pressurized air or liquids, and springs or other stored-energy components. If there is any doubt, put on eye protection. Use other protective wear when necessary, for example, gloves or safety shoes. Handling hot or sharp parts can cause severe burns or cuts. Before you grab something that looks like it can hurt you, stop and put on gloves. Make sure the engine is off before you begin any servicing procedures, unless the instructions tell you to do otherwise. This will help eliminate several potential hazards: Carbon monoxide poisoning from engine exhaust. Be sure there is adequate ventilation whenever you run the engine. Burns from hot parts. Let the engine and exhaust system cool before working in those areas. Injury from moving parts. If the instruction tells you to run the engine, be sure your hands, fingers, and clothing are out of the way. Gasoline vapors are explosive. To reduce the possibility of a fire or explosion, be careful when working around gasoline. Use only a nonflammable solvent, not gasoline, to clean parts. Never drain or store gasoline in an open container. Keep all cigarettes, sparks, and flames away from all fuel-related parts.

A FEW WORDS ABOUT SAFETY

SERVICE INFORMATION

The service and repair information contained in this manual is intended for use by qualified, professional technicians.

Attempting service or repairs without the proper training, tools, and equipment could cause injury to you or others. It

could also damage the engine or create an unsafe condition.

This manual describes the proper methods and procedures for performing service, maintenance, and repairs. Some

procedures require the use of special tools. Any person who intends to use a replacement part, service procedure, or a

tool that is not recommended by Honda, must determine the risks to their personal safety and the safe operation of the

engine.

If you need to replace a part, use genuine Honda parts with the correct part number, or an equivalent part. We strongly

recommend that you do not use replacement parts of inferior quality.

For Your Customer’s Safety

Proper service and maintenance are essential to the customer’s

safety and the reliability of the engine. Any error or oversight

while servicing an engine can result in faulty operation, damage

to the engine, or injury to others.

For Your Safety

Because this manual is intended for the professional service

technician, we do not provide warnings about many basic shop

safety practices (eg, Hot parts – wear gloves). If you have not

received shop safety training or do not feel confident about your

knowledge of safe servicing practices, we recommend that you

do not attempt to perform the procedures described in this

manual.

Some of the most important general service safety precautions

are given below. However, we cannot warn you of every

conceivable hazard that can arise in performing service and

repair procedures. Only you can decide whether or not you

should perform a given task.

Important Safety Precautions

• Make sure you have a clear understanding of all basic shop safety practices and that you are wearing appropriate clothing and using safety equipment. When performing any service task, be especially careful of the following:

! Read all of the instructions before you begin, and make sure you have the tools, the replacement or repair parts, and the skills required to perform the tasks safely and completely.

! Protect your eyes by using proper safety glasses, goggles, or face shields any time you hammer, drill, grind, or work around pressurized air or liquids, and springs or other stored-energy components. If there is any doubt, put on eye protection.

! Use other protective wear when necessary, for example, gloves or safety shoes. Handling hot or sharp parts can cause severe burns or cuts. Before you grab something that looks like it can hurt you, stop and put on gloves.

• Make sure the engine is off before you begin any servicing procedures, unless the instructions tell you to do otherwise. This will help eliminate several potential hazards:

! Carbon monoxide poisoning from engine exhaust. Be sure there is adequate ventilation whenever you run the engine.

! Burns from hot parts. Let the engine and exhaust system cool before working in those areas.

! Injury from moving parts. If the instruction tells you to run the engine, be sure your hands, fingers, and clothing are out of the way.

• Gasoline vapors are explosive. To reduce the possibility of a fire or explosion, be careful when working around gasoline.

! Use only a nonflammable solvent, not gasoline, to clean parts.

! Never drain or store gasoline in an open container.

! Keep all cigarettes, sparks, and flames away from all fuel-related parts.

!WARNING

Improper service or repairs can create an unsafe

condition that can cause your customer or others

to be seriously hurt or killed.

Follow the procedures and precautions in this

manual and other service materials carefully.

!WARNING

Failure to properly follow instructions and

precautions can cause you to be seriously hurt

or killed.

Follow the procedures and precautions in this

manual carefully.

INSPECTION

Transistorized Ignition Coil

Cast Iron Flywheel Type

Primary Side

Measure the resistance of the primary coil by

attaching one ohmmeter lead to the ignition coil's

primary terminal while touching the other test

lead to the iron core.

Secondary Side

Measure the resistance of the secondary side of

the coil by removing the spark plug cap and

attaching one lead of the ohmmeter to the spark

plug wire (high tension lead) and the other test

lead to the iron core.

If the resistance is not within specification,

replace the ignition coil.

ADJUSTMENT

Ignition Coil Air Gap

Cast Iron Flywheel Type

Adjustment is required only when the ignition coil

or the flywheel has been removed.

1. Loosen the ignition coil bolts.

2. Insert a long feeler gauge of the proper

thickness between two legs of the coil

assembly.

• Avoid the flywheel magnet.

• Both gaps must be adjusted simultaneously.

3. Push the coil assembly firmly toward the

flywheel and tighten the bolts.
