    I use ammonia in cleaning out tanks. Like Frank said, the tank uses gaskets and they do dry out and leak. You can get parts from Larson’s outboard service. Make sure there is grease in the gearbox. I use John Deere corn head grease in mine. Fuel oil ratio is 3/4 pint oil to a gallon of gas. I use a 16/1 ratio. Nice little motors, hope it runs well for you.
