Yes Richard has found it . Partial quote from Garry in Tampa "Unfortunately I no longer have any service bulletins prior to 1958. The bulletin instructed you to open the quarter inch hole in the front lower motor cover to two inches, and remove and discard the rubber elbow and fiberglass acoustical liner from the intake air silencer."
Frank and Richard, Thank you both.
