Frequently Asked Questions - GCV190 Honda

What type of oil to use for the Honda GCV190 engine?

Use a 4-stroke engine oil of grade SAE 10W-30 meeting at least API SJ classification or equivalent. The total capacity is 0.50 L. Check the level with the dipstick before each use.

What fuel to put in the tank?

Use unleaded gasoline with a research octane number of at least 91. Ethanol can be present up to 10% (E10). Never use an oil-gasoline mixture. Refuel in a ventilated area, with the engine cold and stopped.

How to start the GCV190 engine?

The procedure varies depending on the control type. In general: open the fuel valve, set the choke to CHOKE position (cold engine), turn the switch to ON, pull the starter handle gently until resistance then pull vigorously. Close the choke once the engine is warm. Consult the manual for your specific type.

How to maintain the air filter?

Check the air filter before each use. To clean, tap the element on a hard surface or use compressed air (max 207 kPa) from the clean side. Do not brush off dirt. Replace it every 2 years or if damaged.

What is the spark plug gap and how to change it?

The spark plug gap should be 0.70 to 0.80 mm. Use a NGK BPR6ES (pressure washer application) or BPR5ES (other). To change, remove the cap, unscrew the plug with a suitable wrench, screw in by hand then tighten by 1/2 turn (new) or 1/8 to 1/4 turn (reused).

How to store the engine off-season?

For storage over 90 days: drain the fuel (run the engine until it stops), change the oil, remove the spark plug, pour 5-10 cc of clean oil into the cylinder, pull the starter a few times, reinstall the plug. Store horizontally in a dry, ventilated place with the fuel valve closed.

SERVICING YOUR ENGINE

THE IMPORTANCE OF MAINTENANCE

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

WARNING

Improper maintenance, or failure to correct a problem before operation, can cause a malfunction in which you can be seriously hurt or killed.

Always follow the inspection and maintenance recommendations and schedules in this Owner's Manual.

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.

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 Honda Genuine parts or their equivalents for repair and replacement.

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.

WARNING

Failure to properly follow maintenance instructions and precautions can cause you to be seriously hurt or killed.

Always follow the procedures and precautions in this Owner's Manual.

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

Failure to follow this maintenance schedule could result in non-warrantable failures.

REFUELING

This engine is certified to operate on unleaded petrol with a research octane rating of 91 or higher.

We recommend refueling after each use to minimize the air present in the fuel tank.

Refuel in a well-ventilated area with the engine stopped. If the engine has been running, allow it to cool first. Never refuel the engine inside a building where petrol fumes may reach flames or sparks.

You may use regular unleaded petrol containing no more than 10% ethanol (E10) or 5% methanol by volume. In addition, methanol must contain cosolvents and corrosion inhibitors. Use of fuels with content of ethanol or methanol greater than shown above may cause starting and/or performance problems. It may also damage metal, rubber, and plastic parts of the fuel system. In addition, ethanol is hygroscopic, which means it attracts and retains water in the fuel system.

Engine damage or performance problems that result from using a fuel with percentages of ethanol or methanol greater than shown above are not overed by warranty.

If your equipment will be used on an infrequent or intermittent basis (more than 4 weeks between usage), refer to the Fuel section of the STORAGE chapter (page 10) for additional information regarding fuel deterioration.

Never use stale or contaminated petrol or oil/petrol mixture. Avoid getting dirt or water in the fuel tank.

WARNING

Petrol is highly flammable and explosive, and you can be burned or seriously injured when refueling.

• Stop engine and let cool before refueling
• Keep heat, sparks, and flame away.
• Refuel only outdoors.
• Wipe up spills immediately.

Adding Fuel

See F1 on page 4.

1. Remove the fuel tank cap.

2. Add fuel to the bottom of the red fuel level gauge [1] in the neck of the fuel tank. Do not overfill. Wipe up spilled fuel before starting the engine.

3. Install the fuel tank cap and tighten it securely.

Move at least 10 feet (3 meters) away from the fueling source and site before starting the engine.

NOTICE

Fuel can damage paint and some types of plastic. Be careful not to spill fuel when filling your fuel tank. Damage caused by spilled fuel is not covered under your Distributor's Limited Warranty.

Fuel Storage Container

Store your petrol in a clean, plastic, sealed container designed for fuel storage. Close the vent (if equipped) when not in use, and store the container away from direct sunlight. If it takes more than 3 months to use the fuel in the container, we suggest adding a fuel stabilizer to the fuel when you fill the container. If you have some fuel left in the storage container at the end of the season, the U.S. Environmental Protection Agency (EPA) suggests adding the petrol to your vehicle's gas tank.

ENGINE OIL

Oil is a major factor affecting performance and service life. Use 4-stroke automotive detergent oil. Always change the oil in accordance with the maintenance schedule.

Recommended Oil

See F2 on page 4.

Use 4-stroke motor oil that meets or exceeds the requirements for API service category SJ or later. Always check the API service label on the oil container to be sure it includes the letters SJ or later.

SAE 10W-30 is recommended for general use. Other viscosities shown in the chart may be used when the average temperature in your area is within the indicated range.

Oil Level Check

See F2, F3 on page 4.

1. Check the oil with the engine stopped and level.
2. Remove the oil filler cap/dipstick [1] and wipe it clean.
3. Insert the oil filler cap/dipstick into the oil filler neck as shown, but do not screw it in, and then remove it to check the oil level.
4. If the oil level is near or below the lower limit mark [2] on the dipstick, remove the oil filler cap/dipstick, and fill with the recommended oil to the upper limit mark [3]. Do not overfill.
5. Reinstall the oil filler cap/dipstick.

Oil Change

See F3 on page 4.

Drain the engine oil when the engine is warm. Warm oil drains quickly and completely.

1. Turn the fuel valve to the OFF position to reduce the possibility of fuel leakage.
2. Place a suitable container next to the engine to catch the used oil.
3. Remove the oil filler cap/dipstick [1] and drain the oil into the container by tipping the engine toward the oil filler neck [4].
   Please dispose of used motor oil in a manner that is compatible with the environment. We suggest you take used oil in a sealed container to your local recycling center or service station for reclamation. Do not throw it in the trash, pour it on the ground, or pour it down a drain.
4. With the engine in a level position, fill to the upper limit mark [3] on the dipstick with the recommended oil.

NOTICE

Running the engine with a low oil level can cause engine damage.

1. Reinstall the oil filler cap/dipstick securely.

AIR CLEANER

A properly maintained air filter will help prevent dirt from entering your engine. Dirt entering the carburetor can be drawn into small passages in the carburetor and cause premature engine wear. These small passages can become blocked, causing starting or running problems. You will need to clean the filter more frequently if you operate the engine in very dusty areas.

We recommend the use of a Honda Genuine air filter to ensure it seals and performs as designed. Using a non-Honda air filter can result in dirt bypassing the filter, causing damage to the engine or fuel system.

NOTICE

Operating the engine without a filter, or with damaged filter, will allow dirt to enter the engine, causing rapid engine wear. This type of damage is not covered under your Distributor's Limited Warranty.

Inspection

See F4 on page 4.

1. Press the latch tabs [1] on the top of the air cleaner cover [2], and remove the cover. Check the filter [3] to be sure it is clean and in good condition.
2. Reinstall the filter and air cleaner cover.

Cleaning

See F4 on page 4.

1. Tap the filter several times on a hard surface to remove dirt, or blow compressed air not exceeding 207 kPa through the filter from the clean side that faces the engine. Never try to brush off dirt. Brushing will force dirt into the fibers.
2. Wipe dirt from the air cleaner body [4] and cover using a moist rag. Be careful to prevent dirt from entering the air duct [5] that leads to the carburetor.

SPARK PLUG

See F5 on page 4.

Required Spark Plug:

NGK - BPR6ES Pressure washer applications

NGK - BPR5ES All other applications

The recommended spark plug is the correct heat range for normal engine operating temperatures.

NOTICE

Incorrect spark plugs can cause engine damage.

For good performance, the spark plug must be properly gapped and free of deposits.

1. Disconnect the cap from the spark plug, and remove any dirt from the spark plug area.
2. Use the proper size spark plug wrench [1] to remove the spark plug.
3. Inspect the spark plug. Replace it if damaged, badly fouled, if the sealing washer [2] is in poor condition, or if the electrode is worn.
4. Measure the electrode gap with a suitable gauge. The correct gap is 0.70 \~ 0.80 mm. If adjustment is needed, correct the gap by carefully bending the side electrode.
5. Install the spark plug carefully, by hand, to avoid cross-threading.
6. 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.

NOTICE

Properly tighten the spark plug. 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.

1. Attach the spark plug cap to the spark plug.

FLYWHEEL BRAKE INSPECTION (if equipped)

See F6, F7 on page 4.

1. Remove the three flange nuts [1] from the recoil starter [2], and remove the recoil starter from the engine.
2. Remove the fuel tank [3] from the engine without disconnecting the fuel tube [4]. If the fuel tank contains fuel, keep it level as you remove it and set it beside the engine in a level position.
3. Check the brake shoe [5] thickness. If it is less than 3 mm, take the engine to your authorized Honda servicing dealer.
4. Install the fuel tank and recoil starter, and tighten the three nuts securely.

SPARK ARRESTER (if equipped)

See F8 on page 4.

In Europe and other countries where machinery directive 2006/42/EC is enforced, this cleaning should be done by your 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.

Removal

1. Remove the three 6 mm bolts [1] from the muffler protector [2], and remove the muffler protector.
2. Remove the special screw [3] from the spark arrester [4], and remove the spark arrester from the muffler [5].

Cleaning & Inspection

1. 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.
2. Install the spark arrester in the reverse order of removal.

STORING YOUR ENGINE

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.

Cleaning

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.

NOTICE

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.

Fuel

NOTICE

Depending on the region where you operate your equipment, fuel formulations may deteriorate and oxidize rapidly. Fuel deterioration and oxidation can occur in as little as 30 days and may cause damage to the carburetor and/or fuel system. Please check with your servicing dealer for local storage recommendations.

The length of time that petrol can be left in your fuel tank and carburetor without causing functional problems will vary with such factors as petrol 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 month of inactivity, or even less if the petrol was not fresh when you filled the fuel tank.

Petrol will oxidize and deteriorate in storage. Deteriorated petrol will cause hard starting, and it leaves gum deposits that can clog the small passages in the fuel system. If the petrol in your engine deteriorates during storage, you may need to have the carburetor and other fuel system components serviced or replaced.

If you keep a container of petrol for refueling, be sure that it contains only fresh petrol. If it takes more than 3 months to use the fuel in your storage container, we suggest adding a fuel stabilizer to the fuel when you fill the container.

Fuel system damage or engine performance problems resulting from neglected storage preparation are not covered under your engine warranty.

Short Term Storage (30 - 90 days)

If your equipment will not be used between 30 and 90 days, we recommend the following to prevent fuel-related problems:

1. Add fuel stabilizer following the manufacturer's instructions.

When adding a fuel stabilizer, fill the fuel tank with fresh petrol. If only partially filled, air in the tank will promote fuel deterioration during storage.

Note:

• All stabilizers have a shelf life and their performance will deteriorate over time.
  – Fuel stabilizers will not reconstitute stale fuel.

• After adding a fuel stabilizer, run the engine outdoors for 10 minutes to be sure that treated petrol has replaced the untreated petrol in the carburetor.

• Turn the fuel valve to the OFF position.
• Continue to run the engine until it stops from the lack of fuel in the carburetor fuel bowl. Running time should be less than 3 minutes.

Long Term or Seasonal Storage (greater than 90 days)

Start the engine and allow it to run long enough to empty all the petrol from the entire fuel system (including the fuel tank). Do not allow petrol to remain in your engine for more than 90 days of inactivity.

Engine Oil

1. Change the engine oil (see page 9).
2. Remove the spark plug (see page 9).
3. Pour 5 \~ 10 cc of clean engine oil into the cylinder.
4. Pull the recoil starter several times to distribute the oil.
5. Reinstall the spark plug.

Storage Precautions

If your engine will be stored with petrol in the fuel tank, it is important to reduce the hazard of petrol 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 petrol in the fuel tank, leave the fuel valve in the OFF position.

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 5).

If the fuel was drained during storage preparation, fill the tank with fresh petrol. If you keep a container of petrol for refueling, be sure it contains only fresh petrol. Petrol 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.

Review the instructions provided with the equipment powered by this engine for any procedures that should be followed for transporting.

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 engine at altitudes above 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 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 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.
