RE: PAW .15 muffler leakage
Todd most likely old and dried out just call Eric Clutton or Carlson and replace them do not mess with permatex or the like coating them messy but will work martin
Just noticed new engine so old and dry not the issue make sure seated right and not damaged
\ Post note I have 3 or 4 PAWs I did put a thin coat of Koppercoat sealer wen installed with a small artist brush repeat just a tiny thin coat both sides of gasket no leaks
