For your safety, and to maximize the service life of your equipment, it is very important to take a few moments before you operate the engine to check its condition.

  • Page 5: Refueling

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

    1. Drain the engine oil (see page 5). 2. Remove the oil filter with an oil filter wrench and let the remaining oil drain out. Discard the oil filter. NOTICE Use a socket-type wrench to remove and install the oil filter. If other types of oil filter wrenches must be used, be careful to avoid hitting and damaging the fuel line or fuel tank connection.

    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. 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.

    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.
