550XP mk2 revisions?

[Backstage]

Hi All,

Looking to pick up a used husky 550XP mk2 from a local rebuild shop that goes through a ton of orange. I understand this saw has gone through several revisions to the carburetor and possibly other systems. I’d like to know what I’m looking at, but can’t find any info on that. Any pointers to what I’m missing?

Crank bearing/seal is now the same on both the flywheel and clutch side instead of 2 different bearings and seals like the old models. Mk2 is a little heavier. Basically a totally different saw almost. Only a few parts interchange between the 550 and 550mk2
