Sterling, I only use WD40 on the gaskets inside of the carb. The rest of the engine gaskets get the copper gasket spray. I have friends who only use WD40 and no copper spray. They seem to do well using their method. I use the copper spray. I don't copper spray head gaskets or copper exhaust gaskets, only ones made of gasket paper. Ted
