I've got a Stihl BR420C blower. Wasn't running very well. Cleaned up the exhaust screen (if was really clogged), running well now. While I had the muffler off found the exhaust port on engine somewhat built up. The muffler is a sealed unit (and catalytic).
Looking for thoughts on how to clean out the muffler. Or should I just replace? If I replace can I install a non-catalytic as that's most of what I see advertised.
TIA for any thoughts and ideas.
