1956 Evinrude Fuel Filter

[Griffschoony]

Hello. I have a 1956 evinrude 30hp outboard. Im looking for the stone fuel filter and gasket that fits inside the glass bowl on the carburator. The engine runs but has no top end power. Noticed the glass bowl leaks a little fuel and the stone looks really nasty. Having a hard time finding a part number or any information on the filter and gasket. If anyone has any ideas,i sure would appreciate the help.
