the 2260 has impressed me so far, it runs like a scalded dog. the 2253, not so much. i am still very intriged at how this new platform is put together, it looks pretty busy in the carb area.

EPA specs cuase that issue. Phuck the epa make shure it dont have cat in it. Tune it up right and run more oil. My eco sounded just like what you explained and now it runs real nice.

No cat, not an epa issue here. It's just an engine......prolly has a vacuum leak.

A buddy of mine had some Amish come cut wood and they pulled in in a new f-350 crew cab diesel, talking on a cell phone and running new stihl saws. They cut logs in six or eight foot lengths so the boys back home could cut into firewood lengths with a buck saw![emoji1]

So only the ones that run poorly meet EPA rules? It's an AutoTune saw and it sounds like there's sonething wrong with it.
The carb on the 550 has a L speed screw, you have to pull the carb to get to it. The 550 is not known to have the same carb issues as the 562. Sorry I smell something funny in this thread, smalls a little like BS.

Oh ok were they known for bad castings or poor machining?

The epa has taken performance away from most engines. Why is it ppl want there saws running a bit richer? Exhaust temps too high and score or burn pistons? Less oil cause of smoke or pollution? . Tears up engines a bit quicker than 40/1 and richer. And now how many tunable saws do you have that may have had limiter caps on them that you removed.

What's b.s. here? It is new saw that is not running right, plain and simple. What is b.s. about that?

If you bought the saw used and have no dealer to turn what are you going to do?

Older saws rule. You dont need a ipad or laptop to tune them.wow I just noticed your sig.
I have a 1 owner very healthy 024 super, and a standard 024. Perhaps we could work something out. I don't have any modern saws.I got this from the original owner complete with stabilized fuel and owners manual.

Some of your posts are incredibly hard to understand.
Can you break this one down ?
I cant crack the code..im trying to understand..

You can't tune the A/T saw that way either Mike.
Like I said, I've torn down several 545, 550, 2253, etc with bad transfer seals. Husky has improved the transfer cover and seal in the last few months....but there are more than a few out there with built in vacuum leaks. Another place to check is the intake boot......I've seen a few assembled incorrectly from the factory, and the boot was rolled in. They also made an improvement there, and added a intake ring to keep that from happening.

Correct mixtures make power. Rich mixtures waste fuel and go slow, but chainsaws have never had carbs that can hold a correct mixture (either lean or rich) until now. To me an engine that is blubbering and misfiring ("4 stroking") is broken and needs to be fixed, but no, they actually make them that way! I would not put up with a misfiring engine on anything else and would take such a defective piece of junk back, but with saws there has not been any alternative.
The EPA did not require lean mixtures that score cylinders, limiter caps, cat mufflers or any of that happy horsecrap. It is just a performance test, with the requirement that you show that the stuff you actually produce will perform as the examples you submitted for testing did. How you meet those limits is up to the manufacturer, and all of that fine "engineering" was brought to you by the manufacturers. In fact it's not even that severe of an emissions limit; they're really only trying to keep raw fuel from puking out the exhaust.
The whole 4-stroking rich mixture misfire is not something that was designed into chainsaws to protect them, it is an unfortunate consequence of making an all-position carb (they removed a feature found in all other carbs). So what if they misfired? Heck, fuel was cheap, and why spend any more on a better carb? It became an easy way to set the mixture by listening for it, but it could have been done other ways.
It still irritates me that they're only putting AT/MT feedback carbs on the high end saws. I mean, it's a cheap solenoid valve, a connector, some wire and maybe a temp sensor and switch, plus a cheap micro and a few other electronics that can be packaged in with the electronic ignition that would be there anyway. Compare this to the electronic systems in so much other stuff and it's really not much - they should be putting at least a simplified version on every homeowner Poulan by now.

Stihl has a great system Chris. They made it simple. The same solenoid fits every M/T carb......and is almost always the problem. It's like 25 bucks, and the user can do the reset himself. Huskys system is over complicated, and must be plugged in to do a reset. I can fix a Husky.....and when the temp swings wildly........the problem sometimes returns. 
Not bashing here........just telling the truth.
