Australian made Atom chainsaw best saw I've ever owned made for Australians that don't like cleaning air filters.. it does it all for ya self cleaning! I wish these new machines came with ahead of its time innovation like the old Atoms! 
wood dust in the carb hard on the saw?

Proprietary cotten fiber blend ( polyester & cotton ) main filter media with a secondary fine polyester prefilter sleeve for severe service usage dirt bikes , atv/utv , dune buggies etc . The Austrialian Unifilters use a dual polyester foam system . The secondary or prefilter sleeve is pretreated with their proprietary oil . I usuaĺly just buy Maxima oil filter treatment , which comes with the filter cleaner & oil treatment . I agree the old K&N single stage filters were not as efficient in dirt intrusion protection , however their new system allows sufficient air flow & maximium filtration , only surpassed by Unifilters in my opinion in the last 2-3 years !
I don't believe the fines actually contact the piston and thus remain airborne and combusted, if they were attaching to the piston skirt then surely the carb venturi and intake stub would both be caked in it?
Those actually work good.
I'd like to meet the engineer that designs one for a chainsaw.
My friend built an anti gravity machine. But, he can't find it.
Flywheel air helps keep the air filter clean? Sounds familiar.
@ ZeroJunk....I think I saw your friends anti-gravity orbiting Saturn
My CS 590 had similar issues like this. But with a bit of cork gasket and a O ring all has improved greatly.![20211130_110748[1].jpg](https://cdn.imagearchive.com/arboristsite/data/attachments/885/885280-39eb45aa01e64e8365eaefa47dbc29e9.jpg "20211130_110748[1].jpg")

Are you nuts? Sucking fines all day doesn't hurt a thing!
Are ya eyes painted on or something? I've put up pics of saws that have ingested huge amounts of sawdust fines with jackall if any sawdust induced damage like alarmists as yourself would have us believe.
Now if you have little faith in the ratio and quality of oil you run then yes I agree clean ya filter it's that simple.
I just use a shmear of grease on the filter where it contacts the saw housing.
Then again, I don't pull the filter off and beat it on a log every 5 minutes. (Not sure when the last time I cleaned the filter is, TBH. Last year?) No fines, and no Collapse of the Universeâ„ because I didn't beat the crap out of the filter 50X per day.
People act as though these things were F1 car engines, FFS.

It feels like a bunch of 12-year-olds talking about putting bigger carbs, blowers and N2O onto their push mowers.
In the first place I am not an alarmist. I just don't think sucking wood dust and associated dirt through a motor is a good thing. Second oil ratio and type doesn't compensate for or protect against sucking wood dust and associated dirt through your motor.
I only clean my filters when the look nasty, but we'll before they begin to suck dust and dirt past the seal.I just use a shmear of grease on the filter where it contacts the saw housing.

It's not something to obsess about, but rather be mindful about.
They had those on cars/trucks too. Work great and a 1/2 quart of oil is readily available and costs less than a filter.
But just think how long they might have lasted, without ingesting junk !
An additional week...?
All them saws are still running perfectly fine today. The 2 ms661 are still doing commercial firewood on a daily basis, one is 1st coil so must be almost a decade old now. I pulled the cylinders in 2022 just for a look so they been running for two more years since then.
I pulled the cylinder off the early ms880 in 2020 and it's still running fine today.
I'm not sure how long saws are meant to last but over a decade or more in harsh working conditions seems more than acceptable.
Apparently some guy's are putting in piston/rings in two year old saws I'm not sure what I'm doing wrong everything apparently lol
In my experience sawdust fines ain't worth worrying about but I run a good oil and plenty of it.
I would not recommend doing what I do for guy's running an under performing oil at 40:1/ 50:1.
Now if we are talking dirt that will destroy any engine in short order and is a completely different subject. I clean my mx bikes filters often any dirt/dust will destroy them fast.

Consider checking your air filter regularly to prevent dust accumulation in the cylinder. While some fine particles may burn off during operation, larger particles can lead to increased wear and tear, potentially shortening the lifespan of your saw.
For better performance, ensure your saw is properly maintained and use a high-quality air filter to minimize leakage and protect the engine.
