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