Thanks in advance you guys are a great help. I did a search but did not find the answer. I am rebuilding the carbs on a 1990 90 hp fource and the fuel bowl gaskets are cork. They are not broken, but are in bad shape and I am concerned the will fail. Will I need to goto a dealer to get new ones or can I use something else. I hope I don't have to buy the kits to get the gaskets, I don't realy need the kits.
