Before the oil level in the crankcase can fall below a safe limit, the Low oil Shutdown system will automatically shut down the engine (the engine switch will remain in the ON position). If you always operate the water pump at altitudes higher than 6, 000 feet above sea level, have your authorized Talon Water Pump dealer perform these carburetor modifications. Even with suitable carburetor jetting, engine horsepower will decrease approximately 3. Operation of the Water Pump at an altitude lower that the carburetor is jetted for may result in reduced performance, overheating, and serious engine damage caused by an excessively lean air/fuel mixture. Engine oil is a major factor affecting engine performance and service life. Be sure to check the engine on a level surface with the engine stopped. Use Mcculloch 4-stroke oil, or an equivalent high detergent, premium quality motor oil certified to meet or exceed U.

Check the oil level by inserting the dipstick in the filler neck without screwing it in. If the level is low, fill to the top of oil filler neck with the recommended oil. The low oil shutdown will automatically stop the engine before the oil level falls below the safe limit. However, to avoid the inconvenience of an unexpected shutdown, it is advisable to visually inspect the oil level regularly. 5-2A) Your engine is designed to use any gasoline that has a pump octane number (R+M/2 ) of 86 or higher, or that has a research octane number of 91 or higher. gasoline pumps at service station normally display the pump A octane number. We recommend that you use unleaded fuel because it produces fewer engine and spark plug deposits and extends the life of exhaust system components. Use of a lower octane gasoline can cause persistent "pinging" or heavy "spark knock" (a metallic rapping noise) which, if severe, can lead to engine damage. Do not smoke or allow flames or sparks in the area where the engine is refueled or where gasoline is stored. [. . . ] Remove the spark plug If the engine has been running, the muffler will be very hot. After the spark plug is seated, tighten with a spark plug wrench to compress the washer. NOTE: If installing a new spark plug, tighten 1/2 turn after the spark plug seats to compress the washer. If reinstalling a used spark plug, tighten 1/2-1/4 turn after the spark plug seats to compress the washer. [. . . ]
