I have just came across a Johnson Sea horse model number HD 25. The carb is leaking gas around the float pin.. I took the carb apart and noticed the cork float is n rather bad shape and needs replaced and on the hand pump I read somewhere there should be four washers brass leather leather brass and all i have is one brass. This is the first boat motor I have messed with, so if someone could give me some ideas on where to find parts or what to make news parts out of and what for sure i do need to stop the leak. Thank you
