REFUELING Use unleaded gasoline with a pump octane rating of 86 or higher. This engine is certified to operate on unleaded gasoline. Unleaded gasoline produces fewer engine and spark plug deposits and extends exhaust system life. flammable and explosive, and you can be burned orseriously injured when refueling. 0 0 Stop engine and keep heat, sparks, and flame away. Handle fuelonly outdoors. Wipe up spills immediately. pii5K-j Fuel can damagepaint andsome typesof plastic.
ENGINE OIL RecommendedOil Use 4-stroke motoroil that meets or exceeds the requirements for API service classificationSJ. Always check the API SERVICE label on the oil containertobesure it includesthe -30 -'O -lo letters SJ. TEMPERATURE AMBIENT lo 2o 30 SAE IOW-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 1. Check the oil level with the engine stopped and level. 2.
Oil Change Drain the engine oil when the engineis warm. Warm oil drains quickly and completely. 1. Place a suitable container nextto the oil drain bolt area. filler cap/ 2. Wipe the oil filler area clean, then remove the oil dipstick. 3. Remove the oil drainbolt and sealing washer, and allow the oil to drain into a suitable container. After draining, install the drain bolt with the sealing washer and tightenit securely. 4. With the engine in a level position, fill with the recommended oil.
AIR CLEANER A dirty air cleaner will restrict air flow to the carburetor and cause poor engine performance. Inspect the filter element each time the engine is operated. You will needto clean the filter element more frequently than usual if you operate the engine very in dusty areas. p E i q Operating the engine without a filter,or with damaged filter, will allow dirt to enter theengine, causing rapid engine wear. This type of damage is not covered underthe Distributor’s Limited Warranty. Inspection 1.
SPARK PLUG Recommended Spark Plug: NGK BPMR4A The recommended spark plug is the correct heat range for normal engine operating temperatures. [ NOTICE I Incorrect spark plugcan 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 wrenchto remove the spark plug. 3. Inspect the spark plug.
Install the spark plug carefully, by hand, to avoid cross-threading. After the spark plug isseated, tighten with the proper size spark plug wrenchto compress the washer. When installing a new sparkplug, tighten 1/2 turn after the spark plug seats to compressthe washer. When reinstalling the original sparkplug, tighten 118 - 114 turn after the spark plug seats to compress the washer. I NOTICE I A loose spark plug can become veryhot and can damage the engine.
SEDIMENT CUP CLEANING 1. Move the fuel valve to the OFF position, then remove the fuel sediment cup and O-ring. Gasoline ishighly flammable and explosive, and you can be burned orseriously injured when handlingfuel. Stop engine and keepheat, sparks, and flame away. Handle fuel only outdoors. Wipe up spills immediately. 2. Wash the sediment cup and O-ring in nonflammable solvent, and dry them thoroughly. 3. Place the O-ring inthe fuel valve, and installthe sediment cup.

Fuel system damage or engine performance problems resulting from the Distributor’s 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 thefuel tank and carburetor. ADDING A GASOLINE STABILIZER TO EXTEND FUEL STORAGE LIFE When adding a gasoline stabilizer,fill the fuel tank with fresh gasoline.
1. With the fuel valveOFF, remove and emptythe sediment cup. 2. Turn the fuel valve ON and drainthe gasoline inthe fuel tank into a suitable container. 3.

Select a well-ventilated storage area away from any appliance that operates with a flame, suchas a furnace, water heater,or clothes dryer.Also avoid any area with a spark-producing electric motor, or where power toolsare operated. If possible, avoid storage areas with high humidity, because that promotes rust and corrosion.

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 to the 1,500 carburetor. If you always operate your engine at altitudes above meters (5,000 feet) have an authorized Honda servicing dealer perform this carburetor modification.
Oxygenated Fuels Some conventional gasolinesare being blended with alcoholor an ether compound. These gasolines are collectively referredto as oxygenated fuels. To meet clean air standards, some areas of the United States and Canada use oxygenated fuelsto help reduce emissions. 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. to be posted on the pump.
Emission Control System Information Source of Emissions The combustion process produces carbon monoxide, oxides of nitrogen, and hydrocarbons. Controlof hydrocarbons and oxides of nitrogen is very important because, under certain conditions, they react to form photochemical smog when subjectedto sunlight. Carbon monoxide does not reactin the same way, butit istoxic. 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. Roughidle. Misfiring or backfiring under load. Afterburning(backfiring). Black exhaust smokeor high fuel consumption. Replacement Parts The emission control systems on your Honda engine were designed, built and certified to conform with EPA and California emission regulations.
