REFUELING Use unleaded gasoline with a pump octane rating engine is certified to operate on unleaded gasoline. Unleaded gasoline produces fewer engine and spark plug deposits and extends exhaust system life. be burned or seriously injured when refueling. Stop engine and keep heat, sparks, and flame away. Handle fuel Wipe up spills immediately.
ENGINE OIL Recommended Oil Use 4-stroke motor oil that meets or exceeds the requirements for API service classification SJ. Always check the API SERVICE label on the oil container to be sure it includes the letters SJ. SAE IOW-30 is recommended for general use. Other viscosities shown the chart may be used when the average temperature in your area is within the indicated range.
Oil Change Drain the engine oil when the engine is warm. Warm oil drains quickly and completely. Place a suitable container next to the oil drain bolt area. Wipe the oil filler area clean, then remove the oil filler cap/ dipstick.
AIR CLEANER A dirty air cleaner will restrict air flow engine performance. Inspect the filter element each time the engine operated. You will need to clean the filter element more frequently than usual if you operate the engine in very dusty areas. p E i q Operating the engine without a filter, or with damaged filter, will allow dirt to enter the engine, causing rapid engine wear.
SPARK PLUG Recommended Spark Plug: NGK BPMR4A The recommended spark plug is the correct heat range for normal engine operating temperatures. NOTICE Incorrect spark plug can cause engine damage. For good performance, the spark plug must be properly gapped and free of deposits. 1.
Install the spark plug carefully, by hand, to avoid cross-threading. 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 plug seats to compress the washer. When reinstalling the original spark plug, tighten the spark plug seats to compress the washer.
SEDIMENT CUP CLEANING Move the fuel valve sediment cup and O-ring. 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. Handle fuel only outdoors. Wipe up spills immediately.
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 before servicing the spark arrester. Spark Arrester Removal two 6 Remove the muffler cover. Remove the remove the muffler deflector, arrester plate and spark arrester.
HELPFUL TIPS & SUGGESTIONS STORING YOUR ENGINE Storage Preparation Proper storage preparation is essential for keeping your engine troublefree 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.
Fuel system damage or engine performance problems resulting from neglected storage preparation are not covered under Limited Warranty. 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.
With the fuel valve Turn the fuel valve into a suitable container. Replace the sediment cup and tighten securely. Drain the carburetor by loosening the drain screw. Drain the gasoline into a suitable container. DRAIN SCREW Engine oil 1. Change the engine oil (see 15).
Storage Precautions If your engine will be stored with gasoline 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.

Carburetor Modification 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 ric mixture will also foul the spark plug and cause hard starting. High altitude performance can be improved by specific modifications carburetor.
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. If you use oxygenated fuel, be sure it is unleaded and meets the minimum octane rating requirements.
Emission Control System Information Source of Emissions The combustion process produces carbon monoxide, oxides of nitrogen, and hydrocarbons. Control important because, under certain conditions, they react photochemical smog when subjected to sunlight. Carbon monoxide does not react in the same way, but it is toxic. Honda utilizes lean carburetor settings and other systems to reduce the emissions of carbon monoxide, oxides of nitrogen, and hydrocarbons.
Probiems That May Affect Emissions 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.
