Stihl ms260 muffler leak fix?

[bplust]

My ms260 has a muffler leak, which has caused a small hole via melting in the engine cover. I believe it's a muffler leak, as the hole is by the muffler, and I've been running it like this for a good while, and the saw hasn't blown up. I have to wear a glove on my left hand because it's so hot. Also, I rebuilt the carb, so I'm not lean.

My question is, can I use RTV red (rated to 650 degree Fahrenheit) to seal the two halves of the muffler? The metal gasket is there and in good shape, so I don't think it's a leak between the cylinder and the muffler. Could I use the RTV or do I have to go with something else?

Has anyone else experienced this problem?

Thanks in advance for any replies,

Bryan

Top of inner half of muffler has a lip that I was not properly seating when putting it back in. Noticed this just now, did it properly, no problems.

*******. But a learning *******, so I guess it's better than the not learning one.
