this is a repost:<br /><br />Thanks to all who keep replying to my many questions!<br />Need the OEM part numbers for the two gaskets on the air silencer (air silencer cover side, and carb side) Also, being a pessimist, I am assuming the leaf valves may need replacing once I get into my carb rebuild. Do you replace just the valves, or the whole assembly, and does anyone know the part numbers for them.<br />And while Im asking questions, is there a standard i.d. for fuel lines feeding the carbs?<br />Thanks again. <br />p.s.- How can I find a parts catalogue for this mototr?<br />Oh yea, the engine is Johnson 1975 50 hp Model # 50 esl75
