Just tore down a 455 last week - bought the saw cheap and stripping for parts. Anywho - I've only tore down about 4 older husqvarnas (268, 266, etc.) - I couldn't believe the carb config on this 455. A major PITA to remove the carb assembly - couldn't remove the convoluted choke lever from the linkage - had to remove everything (minus the throttle linkage) at one time. I'm guessing this box store saw isn't meant to be worked on much - all the Stihl carbs I've removed are SO much simpler. Any one else hate this carb configuration??? Cheers!
