I have an old Hurricane burner I bought in 2009. I have had some issues lately starting it and it kicking back. I dismantled the burner and I see that the gasket between the inlet "neck" and the burner gasket was not sealing right. I cleaned all that off but I am wondering what type of high temperature sealant I might use when I have this burner all cleaned up (Using PBW). The original gasket looked like some type of asbestos type material. At least that is what it looked like to me. Any suggestions will be appreciated.
