Husqvarna has changed their filters on autotune saws. Not sure if it applies to their entire saw line but autotune saws have a blue top which is a finer filter element. I’ve seen white, orange, and blue top husky filters.
that makes sense, stihl did the same thing.
The husky autotune saws also have a hollow cylindrical magnet in the fuel hose as well. That’s a pretty recent change though, within the last year if I remember correctly. Like 2023 and newer production.
Haven't seen anything that new yet. My logging buddy usually get a new saw every 2-3 years. Last saw is a 2020 or 2021, my last auto tune was a 2012 562xp, still had the white filter. I'll have to stop off at the dealer and pick up a few spare of whatever the latest fikter version is. Like having filters on hand.
I run a bunch of the aftermarket Walbro style felt filters that you can take apart. Don’t know what the micron rating is in them though
They needed the magnet. I don’t know how many 572s I’ve seen where the carburetor screen was full of brown rust. They say it’s in the fuel. I always figured it was industrial dust from the hoses and filters sitting around shelves for a year
