I understand the reasoning on replacing the cat muffler and the problems it causes BUT.....
I'd go back to the dealer.... tell him there appears to be a design problem with these saws.... as for him telling you your on your own if this one fails, I'd tell him HE has a problem and you expect him to take care of it. I'd even go so far as a registered letter stating the problem and his ignoring the symptoms of it about to happen again along with his statement of being on your own if it fails again. I'd also contact husqvarna with a copy of that letter and demand something is done, either fix it or replace it with a model that won't self-destruct.
Don't be so nice.... you bought a high priced name brand saw from a factory authorized dealer, your doing things according to the book. Expecting the POS to not burn up and self destruct is NOT a unreasonable request!!!! Granted the dealer didn't design the saw, and may be on the receiving end of the factory design issues BUT you do not buy or deal with the factory, they set it up that way. Let the dealer go back to the factory and complain until they make things right.
Squeaky hinge gets the oil....
