STORAGE

Fuel System

Gasoline left in the fuel system for extended
periods without a stabilizer will deteriorate,
resulting in gum deposits in the system.
These deposits can damage the carburetor
and the fuel hoses, filter and tank. Prevent
deposits from forming in the fuel system
during storage by adding a quality fuel
stabilizer to the fuel. Follow the
recommended mix ratio found on the fuel
stabilizer container.
To treat the fuel system for storage:
1. Add fuel stabilizer according to
manufacturers's instructions.
2. Run engine for at least 10 minutes after
adding stabilizer to allow it to reach the
carburetor.
NEVER store the engine with fuel in the fuel
tank inside of a building with potential
sources of ignition.
1. Check safety interlock system (see Safety
Interlock System on page 12).
2. Fill fuel tank (see FILLING FUEL TANK on
page 13).
3. Charge battery (see Charging the Battery
on page 22).
4. Tighten battery cables and/or clean battery
and battery cables (see Cleaning Battery
and Battery Cables on page 21).
5. Connect spark plug wire(s) or replace spark
plug(s). Refer to Engine Manual for detailed
instructions.
