Reinstall the oil filler cap/dipstick securely. 5 AIR CLEANER SPARK PLUG A dirty air cleaner will restrict air flow to the carburetor and cause poor engine performance. Inspect the filter each time the engine is operated. You will need to clean the filter more frequently if you operate the engine in very dusty areas. Recommended Spark Plug: NGK BPR6ES NOTICE NOTICE Operating the engine without an air filter, or with a damaged filter, will allow dirt to enter the engine, causing rapid engine wear. This type of damage is not covered under the Distributor’s Limited Warranty (see page 11). Incorrect spark plugs can cause engine damage. Inspection 1. Disconnect the cap from the spark plug, and remove any dirt from the spark plug area. The recommended spark plug is the correct heat range for normal engine operating temperatures. For good performance, the spark plug must be properly gapped and free of deposits. 1. Press the latch tabs on the top of the air cleaner cover, and remove the cover. 2. Remove the foam element from the air cleaner cover. 2. Use the proper size spark plug wrench to remove the spark plug. 3. Remove the screen grid from the paper element. 4. Check both elements to be sure they are clean and in good condition. 3. Inspect the spark plug. Replace it if damaged, badly fouled, if the sealing washer is in poor condition, or if the electrode is worn. 5. Reinstall the screen grid over the paper element. Make sure that the screen grid completely surrounds the paper pleats. 6. Reinstall the foam element in the air cleaner cover. 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. 7. Set the paper element and screen grid in the air cleaner body then install the air cleaner cover. AIR CLEANER COVER LATCH TABS 0.028 ~ 0.031 in (0.70 ~ 0.80 mm) SEALING WASHER 5.

When reinstalling the original spark plug, tighten 1/8 - 1/4 turn after the spark plug seats to compress the washer. AIR CLEANER BODY 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. Cleaning 9. Attach the spark plug cap to the spark plug. 1. Paper Element: Tap the paper element several times on a hard surface to remove dirt, or blow compressed air [not exceeding 30 psi (207 kPa, 2.1 kg/cm²)] 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. Foam Element: Wash the element in a solution of household detergent and warm water, then rinse thoroughly, or wash in nonflammable or high flash point solvent. Allow the element to dry thoroughly. Soak the element in clean engine oil and squeeze out the excess oil. The engine will smoke during initial start-up if too much oil is left in the foam, or the oil could saturate the paper element making the engine inoperable. 3. Wipe dirt from the air cleaner body and cover using a moist rag. Be careful to prevent dirt from entering the air duct that leads to the carburetor. 6 SPARK ARRESTER (optional equipment) Fuel 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. 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 spark arrester must be serviced every 100 hours to keep it functioning as designed. 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. If the engine has been running, the muffler will be hot. Allow it to cool before servicing the spark arrester. Spark Arrester Removal MUFFLER 1. Remove the three 6 mm bolts from the muffler protector, and remove the muffler protector. 2. Remove the two special screws from the spark arrester, and remove the spark arrester from the muffler. SPECIAL SCREW (2) MUFFLER PROTECTOR 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. SPARK ARRESTER IDENTIFICATION PLATE ADDING A GASOLINE STABILIZER TO EXTEND FUEL STORAGE LIFE SPARK ARRESTER When adding a gasoline stabilizer, fill the fuel tank with fresh gasoline. If only partially filled, air in the tank will promote fuel deterioration during storage. If you keep a container of gasoline for refueling, be sure that it contains only fresh gasoline. 6 mm BOLT (3) Spark Arrester Cleaning & Inspection 1. Add gasoline stabilizer following the manufacturer’s instructions. 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. After adding a gasoline stabilizer, run the engine outdoors for 10 minutes to be sure that treated gasoline has replaced the untreated gasoline in the carburetor. 3. Stop the engine. 2. Install the spark arrester in the reverse order of removal. HELPFUL TIPS & SUGGESTIONS STORING YOUR ENGINE Storage Preparation 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. 7 Storage Precautions DRAINING THE FUEL TANK AND CARBURETOR 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. WARNING Gasoline is highly flammable and explosive, and you can be burned or seriously injured when handling fuel. • Stop engine and keep heat, sparks, and flame away. • Refuel only outdoors. • Wipe up spills immediately. If possible, avoid storage areas with high humidity, because that promotes rust and corrosion. Keep the engine level in storage. Tilting can cause fuel or oil leakage. 1. Use a siphon pump (commercially available) and siphon the fuel out of the fuel tank into an approved gasoline container. 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. 2. Place an approved gasoline container below the carburetor, and use a funnel to avoid spilling fuel. 3. Loosen the carburetor drain screw. and drain the carburetor into an approved gasoline container. After draining is completed, tighten the carburetor drain screw. SIPHON PUMP (COMMERCIALLY AVAILABLE) Removal From Storage Check your engine as described in the BEFORE OPERATION CHECKS section of this manual (see page 2). FLOAT BOWL 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 DRAIN SCREW Keep the engine level when transporting to reduce the possibility of fuel leakage. TAKING CARE OF UNEXPECTED PROBLEMS ENGINE WILL NOT START 1. Check control positions Engine Oil 1. Change the engine oil (see page 5). 2. Remove the spark plug (see page 6). 3. Pour a tablespoon (5 - 10 cc) of clean engine oil into the cylinder. 2. Check engine oil level. 4. Pull the recoil starter several times to distribute the oil. 3. Check fuel. 5. Reinstall the spark plug. 4. Remove and inspect spark plug. 5. Take engine to an authorized Honda servicing dealer, or refer to shop manual. ENGINE LACKS POWER 1. Check air filter 2. Check fuel. 3.

TECHNICAL & CONSUMER INFORMATION 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. TECHNICAL INFORMATION Serial Number and Type Location Record the engine serial number and type in the space below. You will need this information when ordering parts and when making technical or warranty inquiries. 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. 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. SERIAL NUMBER AND TYPE LOCATION SERIAL NUMBER TYPE MODEL SERIAL NUMBER ENGINE TYPE GS190 GCACA– ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ 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. 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. 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). 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. 9 Emission Control System Information Air Index Source of Emissions An Air Index Information hang tag/label is applied to engines certified to an emission durability time period in accordance with the requirements of the California Air Resources Board. 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. The bar graph is intended to provide you, our customer, the ability to compare the emissions performance of available engines. The lower the Air Index, the less pollution. Honda utilizes lean carburetor settings and other systems to reduce the emissions of carbon monoxide, oxides of nitrogen, and hydrocarbons. The durability description is intended to provide you with information relating the engine’s emission durability period. The descriptive term indicates the useful life period for the engine’s emission control system. See your Emission Control System Warranty (page 12) for additional information. 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. Descriptive Term The following instructions and procedures must be followed in order to keep the emissions from your Honda engine within the emission standards. Tampering and Altering Applicable to Emissions Durability Period Moderate 50 hours (0–65 cc) 125 hours (greater than 65 cc) Intermediate 125 hours (0–65 cc) 250 hours (greater than 65 cc) Extended 300 hours (0–65 cc) 500 hours (greater than 65 cc) The Air Index Information hang tag/label must remain on the engine until it is sold. Remove the hang tag before operating the engine. Tampering with or altering the emission control system may increase emissions beyond the legal limit. Among those acts that constitute tampering are: Specifications Length x Width x Height • 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 Dry weight Engine type Displacement [Bore x Stroke] Maximum output Maximum torque Fuel consumption Cooling system Ignition system PTO shaft rotation If you are aware of any of the following symptoms, have your engine inspected and repaired by your servicing dealer. • Hard starting or stalling after starting. • Rough idle. • Misfiring or backfiring under load. • Afterburning (backfiring). • Black exhaust smoke or high fuel consumption.
