ASSEMBLY
STEP 2: Inspect and Tighten Hardware
• Using common hand tools, test all nuts, bolts and
screws on your equipment for tightness. Secure any
loose hardware. Note: Use a 7/16" socket with an exten­
sion to check hardware connecting ends of handlebar.
IMPORTANT: DO NOT TIGHTEN THE ENGINE GOV­
ERNOR SCREW (A) SHOWN IN FIGURE 3. THIS
SCREW IS FACTORY-ADJUSTED FOR PROPER
ENGINE OPERATION.
Figure 3: Do not adjust
or tighten the factory-
set engine governor
screw (A).
WARNING: Experience indicates that alcohol-blended
fuels (called gasohol or using ethanol or methanol) can
attract moisture which leads to separation and formation
of acids during storage. Acidic gas can damage the fuel
system of an engine while in storage. To avoid engine
problems, the fuel system should be emptied before
storage for 30 days or longer. Drain the gas tank, start
the engine and let it run until the fuel lines and carbure­
tor are empty. Use fresh fuel next season. See STOR­
AGE instructions for additional information. Never use
engine or carburetor cleaner products in the fuel tank or
permanent damage may occur.
STEP 3: Add a Mixture of Gasoline and
Two-Cycle Motor Oil to the Fuel Tank
A WARNING
Gasoline and its vapors are highly flammable and
explosive. Keep gasoline away from possible
ignition sources.
Do not smoke while mixing the gasoline and two-
cycle oil together or when filling the fuel tank.
Failure to follow these precautions could result in
the fuel igniting, causing personal injury or prop­
erty damage.
•
• Because your equipment has a two-cycle (“two-
stroke”) engine, it runs exclusively on a mixture of regu­
lar unleaded automotive gasoline and quaiity two-cycle
motor oil. IMPORTANT: THE CORRECT MIXTURE
RATIO IS 24 PARTS GASOLINE TO 1 PART TWO-CY­
CLE OIL. If two-cycle motor oil is not added to the gaso­
line in the proper ratio, engine damage wili occur.
• Use unleaded regular gasoline. Only use unleaded
premium gas if unleaded regular is not available.
• Do not use a multi-viscosity two-cycie motor oil or reg­
ular automotive motor oil. These may not lubricate the
engine properly and may foul the spark plug. Also do
not use gasoline containing METHANOL (wood alcohol).
• Do not mix fuel directly in the fuel tank. Always use a
clean, safety-approved fuel container.
• Use the chart at left to mix together the correct
amounts of gasoline and two-cycle motor oil.
To Mix: First fill a clean container with one-fourth of the
amount of gasoline you will be mixing. Then add in ALL
of the two-cycle engine oil required for the entire amount
of gasoline you wili be using. Mix thoroughly. Finally,
add in the remaining three-quarter’s of the gasoline and
mix that in thoroughly.

To Fill Engine Fuel Tank:
• Engine must be cool.
• Clean area around fuel tank gas cap.
Remove the gas cap. Insert a clean
funnel into the fuel tank.
• Slowly pour gasoline/oil mixture into
fuel tank. Fill tank no higher than 1/2"
from top of tank to allow for gasoline ex­
pansion. Clean up fuel spills right away.
STEP 4: Connect Spark Plug Wire
• Connect the spark plug wire to the
spark plug securely. Refer to Figure 4
below.
