I contacted JD yesterday with Stihl, He was very helpful and willing to address my concerns. So, there is some EPA regulations Stihl is trying to address but he wouldn't clarify any EPA issues with this model. Pretty much Stihl whole line is under EPA regulation...he was very general. I believe all 2 cycle are experiencing EPA focus now, but that my opinion. Not much was mentioned about the design changes on this MS362 but it should cut better than what I'm experiencing. JD is saying 40 hrs to break in this saw...anyone ever heard of that? I spoke to a buddy that has a falling company in Detroit Oregon area, pretty much he runs a new saw hard 8 hrs and consider it broke-in. That pretty much what my dad did too. JD suggested I run this saw or sent it to him, JJD has a lot test logs all sizes and he'll get to the bottom of this problem. Stihl will either replace my saw or fix it. JD opinion is the chrome cylinder is slick and the rings haven't had enough time to seat. Nothing was confirmed about the compression reading on this saw as being normal or not normal...pretty much the saw should cut better but the reason why is the rings haven't had time to seat. I seriously doubt Stihl will run my saw 40hrs. but bottom line they will fix this saw regardless. I sent a email capturing our conversation to JD plus the history/date around this MS362. I think JD should be aware of what's occurring with his dealer and their awareness to problems such as mine... how these shops are addressing this issues. Plus my concern is some guy buys a new saw and get killed by it due to ..well it not broke in! In my opinion that's a serious concern! I do think there is a serious issue with this saw. I don't know if all new saws are like that, but according to the shop they are! I guess I should have confirmed that comment "all new saws are like this" with JD but I did not. Normally I have a list of questions prior to meeting such this so every thing is captured; however, I totally slammed here at work with equipment upgrade and new equipment installation. We just short staffed here at work and my wife and I are experiencing parent health issues...I just got lot on my mind these last few day. As for Lone Wolf question regarding my compression reading ...my adapter to 10mm does not have a Schrader value built in but the fitting on the end which the adapter treads in to does. So...he could be correct. I just haven't had chance to run a test on my 10mm Stihl weed eater. If I had time I'd machine a fitting and install a Schrader valve but I don't right now.

good to hear JD is willing to work with you James. My 462 has about 10 tanks (so about 10 hrs.?) thru it and it has been running fine. i only took it easy the first tank. After that no holds barred. good luck with the parent health issues and the saw.
 
I ordered an MS 362 C-M yesterday. Partly because of this thread! I will perform a compression test as soon as I get it! But it sounds like I might need another compression gauge if it has a smaller spark plug.

40 hours to break in? I'm in the woods only 15 days or so per year and I have several saws. It'll take me years just to break it in...

It will be interesting to compare the new 362 to my older 361. The 361 does not have many hours on it so it is still in great shape. Should be good for a decent comparison.

Please do not do any modifications before you test it out! :rolleyes:

Snap On has the adapter that is a hose with fittings it works for my stuff great. Order the correct thread length measuer a small plug thread depth and compare to the specs on what you buy.. Or I could measure my adapter if you need let me know!

IDK fo sho but I heard the 362 has better low end torque and the 361 revs better? Not positive of this but wait and see.

Thanks, we have lots of brands here in Sweden but not Snap On unfortunately. But I'll find something that'll work.

Well bud that Schrader valve sure is in question and I am very anxious to see what happens . You need to put it in another good running machine and see if it reads low again. Also that will mean they didn't do the test correct at the shop if they even did!

No... I believe Cascade ran the 4 tests... I know Austin there seems pretty straight honest kid...really what can he say thou. I watched Corvallis do their test and they have the same setup as me. So...your probably correct, I need to check my equipment against a good running machine as suggested. I looked the other day for a 10mm Schrader tester but doesn't look like I can confirm what's out there is correct and has the Schrader in the adapter. I'll probably have to make my own which won't be to bad on collet lathe as long as I can get a tap to match the Schrader threads. I might have to pull valve stem off inter-tube, press fit with some JB weld.

Some good advice here about adapters already available.
 
I forgot what forum I was on but a couple of weeks ago I had read where a guy had three or four MS462's and the first one he said took 25 tanks for the saw to fully break in which sounded a long time for any motor. The others broke in much quicker, in the end they all ended up running the same. So maybe your saw does need a little more time on it?? I have a new 462 and have only run a couple of tanks thru it, so to early to tell if it gets any better, one thing for sure is these newer saws operate much better at a higher rpm than the old saws..

Ok. So scratch all this. I placed the order yesterday at a very, very good price point. Just now I received word that their stock was sold out and that I would get a refund. Bummer.
