RECOMMENDED FUEL TYPE
Old fuel is the primary reason for poor unit performance. Be sure to use fresh, clean, unleaded gasoline.
NOTE: This is a four cycle engine. In order to avoid damage to the unit, do
not mix oil with gasoline.
Definition of Blended Fuels
WARNING: DO NOT USE E85 FUEL IN THIS UNIT. It has
been proven that fuel containing greater than 10% ethanol will likely damage this engine and void the warranty.
Today's fuels are often a blend of gasoline and oxygenates such as ethanol, methanol or MTBE (ether). Alcohol-blended fuel absorbs water. As little as 1% water in the fuel can form acids when stored. Use fresh fuel (less than 30 days old), when using alcohol-blended fuel.
Using Blended Fuels
If choosing to use a blended fuel, or its use is unavoidable, follow recommended precautions:
Always use fresh unleaded gasoline
Use the fuel additive STA-BIL® or an equivalent
Drain tank and run the engine dry before storing unit
Using Fuel Additives
The use of fuel additives, such as STA-BIL® Gas Stabilizer or an equivalent, will inhibit corrosion and minimize the formation of gum deposits. Using a fuel additive can keep fuel from forming harmful deposits in the carburetor for up to six (6) months. Add 0.8 oz. (23 ml) of fuel additive per gallon of fuel according to the instructions on the fuel additive container. NEVER add fuel additives directly to the unit's gas tank.
WARNING: Gasoline is extremely flammable. Ignited vapors
may explode. Always stop the engine and allow it to cool before filling the fuel tank. Do not smoke while filling the tank. Keep sparks and open flames at a distance from the area.
FUELING THE UNIT
WARN ING: Add fuel in a clean, level and well ventilated
outdoor area. Wipe up any spilled fuel immediately. Avoid creating a source of ignition for spilled fuel. Do not start the engine until fuel vapors dissipate.

Both rocker arms move freely, and both valves are closed. If these statements are not true, repeat this step.
6. Slide the feeler gauge between the rocker arm and the valve return
spring. Measure the clearance between the valve stem and rocker arm
(Fig. 22). Measure both the intake and exhaust valves. The recommended clearance for both intake and exhaust is .003 - .006 in. (.076 - 0.152 mm). Use a standard automotive .005 in. (0.127 mm) feeler gauge. The feeler gauge should slide between the rocker arm and valve stem with a slight amount of resistance, without binding (Fig. 22).
