GumOut Starting Fluid

To use Gumout Starting Fluid, spray it directly into the air intake, carburetor, or air cleaner for 2–3 seconds before attempting to start the engine. Avoid flooding the engine, and do not use it while the engine is running or with the air filter removed. Precautions: NEVER use while the engine is already running. Do not spray with the air filter removed to prevent backfire. Do not flood the engine (excessive spraying). This product is designed for gasoline engines only, not for diesel engines
