Re: Best Way to Reattach Muffler?
I think the best thing to do is to try and find a new gasket or at least make one from the right kind of gasket material. The fuel is usually still burning as it exits the exhaust port at a really high temperature. Too hot for the gasket maker I think.
If you look real closely at my muffler in the attached pic you can see the effect of the heat. I painted it with 1200 degree high temp paint. It's really dull from the motor to where the baffle is then it becomes semigloss for the last inch and a half. I'd say the exhause it about 800+ degrees when it exits the cylinder. Too hot for gasket glue.
