I seen it happen it drove me nuts for a few days! Wouldn't it be something if it turned out the compression was normal and the shop took it wrong and lied?
Low compression on my new Stihl MS362

I understand the frustrations with the new saws, my first new one was a 241, i was so excited at all the new tech and hype and it disappointed out of the box so i sold it with less than 2 tanks on it. In hindsight i didn't give it enough time to break in. I also had a 361 that i had to rebuild three times since it kept on scoring the piston, couldn't figure it out until the end was a bad decomp valve but it turned me off of ever having a 361 or using a decomp valve. I feel in this situation the compression is probably OK, there is something else going on with the saw but tough to tell online.....but regardless i feel the pain of the excitement and the let down and then you just want to rid yourself of the saw and the situation. I would have thought the mtronic 362 would be more prone to potential issues like this due to additional wiring but a regular carb and ignition can have issues too, they make millions of saws, there will be some with problems, so they have specialized dealers for it.
I have a bunch of 241's and I think they are nice light nimble little saws with exceptional cutting ability for their size! My go to saw for limbing.
So should we take bets on whats wrong with it ? I dont believe the dealer that low compression like that is correct and made like that!
OP send me your compression tester with the adapter and I will clear this up. PM me!
If only one of us had that saw for a couple of hours this chit would be figured out and fixed tuit suit. I can follow that the OP did not want to pull the saw apart for fear of Stihl turning down this case due to owner tampering. It really depends on the dealer, one screw removed and they can disallow any warranty work. Been there and done it as they say.
Yes you are right. But I dont know if that compression is correct. And if his gauge is incorrect so are the dealers! And that part about being normal IDK!!!!!!!!!
Was at a dealers shop one day looking for some presets , parts guy said come out back with me, got boxes with leftover ones out there, pick out what you want from them. The company tech was in a convo with the store owner, owner saying to the tech, find something/anything to get this guy off my back. Tech was looking the saw over real close, almost like a detective and he says to me, knows I work on them a lot. Does this muffler look too clean to you? Kinda I say ,so he removes the front cover and the muffler was clean as brand new, there was carbon buildup in the exhaust port, this saw had maybe 20 hours on it. Guess what?
Many questions we cannot answer due to not having the saw in our hands, cannot get the needed answers to diagnose a case like this online, hands on is how I fix them.
Well he could ship me the tester and that may eliminate the low compression for one thing. Not a lot to ship.
Certainly, that would be just one answer to this case, many others not enough or not the answer I would need.

Well I think he's up towards Canada? Ship you the powerhead.
AddictingWhy do I keep clicking on this thread!!?!?!???
Because we need the answer that's why!
Would love to have that saw right here, it would be fixed in a heartbeat. No saw has ever beat me, I always win no matter the cost. Money has never stopped me from fixing any machine I have torn into.
I don't doubt you for a second!
Whats your best guess of the problem?
Chainsaw problems are so low end mechanically speaking but I also realize the OP has bought and paid for a new Stihl saw that should work and perform right out of the box. One expects this when buying new and feels safe due to warranty and the stated policy the saw can be returned if not satisfied, bit of smoke and mirrors there but at least implied. I have learned otherwise from extended experience.
