I've got an old .40 K & B engine that I recently acquired off e-bay. It has never been run and appears to be 20-30 years old. The needle valve is directly on the carb and I'd like to move it back if possible. Can this be done? If so, what parts do I need and how do I do this. Also, is a gasket required between the engine and muffler? The box did not include one. Thanks, Jim
