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.

CAUTION: Use care when 
releasing idler spring tension. 
Keep body parts well away from 
idler when performing this 
operation.
