CARBURETOR ADJUSTMENT

If clean fresh gasoline combined with a Fuel Stabilizer Additive is used, the

Carburetor will almost never require servicing. Usually most operational problems

involve carbon build-up, weak spark, or excessive priming causing the engine to

flood. All of these possibilities should be checked before working on Carburetor.
