Alternate title: Maybe I'm Just an Idiot I had the good fortune of getting to work on a 455 the other day; man what an impossible saw. It took 20 minutes to get the carburetor off with all that wack fuel line routing, that weird air filter mount & linkages that don't just pop off the carb. The unusual 2 port intake means it's impossible to p/v test without some no-doubt proprietary flange. The muffler that has to be rolled over the bucking teeth means the gasket will definitely fall off the first time you try and put it back on the jug. I know there are a lot of Husqvarna guys on here, and I don't mean to start a political thread about which saw is better. But I'd say from a mechanic perspective, Stihl has 'em beat 9 times out of 10.
