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

manufacturer’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.
