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.
