is hydrophilic, which means that it tends to draw in moisture. If the water contamination
is severe enough, the ethanol will separate from the gasoline and drop to the bottom of
the fuel tank. Since water and oil do not mix well, this ethanol and water blend can
cause severe engine problems due to the lack of lubrication.
To prevent any damage to the engine, it is highly recommended to only use fresh gasoline.
Gas stabilizers can be used to increase the gasol
ine’s shelf life; however, it will not restore
back bad gasoline.
Supply recommended fuel to engine
1. Carefully mix the fuel as recommended in
the Fuel Mixture section.
2. Connect fuel supply line to fuel tank.
3. Prime fuel supply line to evacuate air
bubbles.
4. Connect fuel supply line to engine fuel
connection.
5. Pump fuel up to carburetor.
Note:
Careful not to flood the engine when pumping fuel up to the carburetor; gently squeeze
the priming bulb.
Warning:
Ensure that the fuel tank is positioned away and at a safe distance of the muffler to avoid
any potential accident. Always refuel with care.
Flooded engine
Flooding an engine refers to an accumulation of excess fuel in the cylinder and crankcase
due to excessive fuel priming or use of choke. This condition makes the engine nearly
impossible to start without clearing the engine of the excess fuel.
Clearing a flooded engine:
a) Disconnect the spark plug cable and remove the spark plug.
b) Re-connect the spark plug cable to the spark plug. Place the spark plug in contact with
the cylinder head in order to ground the spark plug.
Note:
Failure to ground the spark plug can lead to damage of the CDI ignition coil when cranking
the engine.
c) With both choke and throttle in fully open position, pull starter rope several times until
excess fuel is exhausted.
d) Before reinstalling spark plug, clean and dry electrode and insulator tip.
e) If engine is severely flooded, remove the engine drain plug and drain engine.
