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’
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.
STORAGE
WARNING: AVOID INJURY. Read and
understand the entire Safety section before
proceeding.
