SEA FOAM will act as starting fluid and will start the engine unless there is a mechanical or electrical problem. With engine warm， keep on high idle and slowly pour one ounce through carburetor throat. Make sure exhaust is well ventilated when using in the carburetor as fumes will be extreme for a short time.
