Guys,
I was working with my K&B 40 fitting the OS FP25 muffler and wanted to reposition the angle of the exhaust so I started to loosen the rear nut and found it just kept turning without releasing the tail cone. It wouldn't come out just spin. I loosened the front bolt and it released the tail cone and I was able to repostion it where I wanted. I retightened the nose bolt the whole muffler is tight but the tail nut still spins, does anyone know what the tail cone nut does in these mufflers?
Best, DennisT
