question on 361 & 362

[tmroper]

I have seen a lot of comments on here about folks not liking the 362 compared to the 361 and I was curious why?  I am sorry but didn't have the best of luck when doing a search to see if anyone had already said.  What are the differences in the two saws and how does it affect them? 
Thank you for your help

I don't recall seeing any posts of anyone that has used the 362. Comments may be based on expected results. We are all about "change" now....not for he better either. It's the kind of change we are all used to getting of late.
Not available yet at my dealer. Still has 361's available.
Change touted is a larger air filter and housing, and a little more weight and maybe a fraction more hp. Suspected to be more in line with new EPA standards, so prolly less performance. Dealer says it is not a big change, but some mention of it being an ongoing smooth transition (rollover). At least that is how I interpreted what he said.

The 362 is 3/4 pounds heavier, and only .2 horsepower stronger. That's not so good. I've been seeing them for sale barely used on ebay. Not a good sign. That's why I decided to get a new 361 instead of the 362.

I looked at and briefly ran the 362 here yesterday at the dealer I buy my Stihls from. It is noticably heavier than the 361, and wider/bulkier. The spring A/V systems is about the same, tucked in under the saw. I did not notice that it was any smoother cutting than a 361. The weird thing is that the air filter is bolted on, so it does not have the snaps that the 441 has, or the easy screw-off air filter cover that the older pro saws have. Supposed to clean it less than often than the 361, as it has the centrifugal air cleaner on it. But you need the scrench to get the air filter cover off. So much for going more tooless... The torque curve is a bit different but not that much different. The one I ran had a 25 inch bar with full skip. Price tag is heavier, by about $80. *Cough* The 362s are popping up here locally on Craigslist too. Used they are the same price as a new 361. 

The new 361s around here are all drying up, and fast. An era has passed. The dealer was miffed that the 361 is going away, even though it is a relatively new saw, and very very popular. They have not sold very many 362s. Same thing happened when the 441 come out. They sold tons of 440s, and few 441s. Now they sell more 460s and not that many 441s. BTW: the 310 and 390 are next to go away. They have already replaced them in Europe with the heavier and more expensive 311 and 391. The 2010 EPA laws are in effect now. Husky and Stihl are both replacing most of their saw lines with new saws.

windthrown or others,
If you aren't so excited about the 362's cost to performance balance which model would you reccomend?

WELL  WE WILL HAVE TO AGREE TO DISAGREE ON THIS. OWN A 2 OF EACH OF THESE MODELS. THE 362 IS A LITTLE HEAVIER ON PAPER,BUT NO ONE IS GONNA TELL ME THEY CAN FEEL A COUPLE OF OUNCES.i run each of mine with 20 &25"bars,all full skip chains. with both saws buried in hardwood,either bar,the 362 just makes alot more torque. it revs way quicker also,very responsive. aside from the high price ,these new saws are awesome. i hope they last like the old ones,the 362 is very well built,that may be where the extra heft comes from. as far as air filter access goes,i can cut all day,and the filter is hardly even dusty. try that w/361. i think the 362 handles the 25"bar a little better. it also is definately better on fuel,i had to run about 20 tanks thru mine before it came to life. the 361 is definately a good saw,but in my opinion the 362 is a step foward for stihl.

I won't need a saw for a while, so I can keep an eye on owner satisfaction with the 362. If not that, 357 Husky or 2156 Jonsered spec out for weight and power almost the same as the 361, and I believe they are EPA approved. Also the 656 Solo has the same power, but weighs half a pound less.

[STIHLFULLSKIP]

not trying to hijack this thread,but i just bought an echo cs600. it is a very nice saw for the money.it pulls a 24"bar good. it runs a lot like the 361.it can be bought for 450-500.

Yes, if you put the two saws side by side the difference in weight is not very noticeable. But run that 362 10 hours a day and than switch to the 361 for the last half hour  and you will not want to take that 362 out of the shop. That weight difference is huge at the end of the day.

Do you have to SHOUT?

The extra weight in the 362 is not due to better build quality. It is becasue the engine has air intake ports for EPA regulations. That makes the engine casting larger, which adds more weight. It is also a wider saw, so the top handle is wider, and the case is wider, and that all adds weight. More weight is not a good thing in a chainsaw, sorry. Also 3/4 of a pound is more than a couple of ounces. Its 12 ounces, actually. And side by side at the dealer, the 362 was obviously heavier than the 361, and bulkier. The 362 has more power to make up for the added weight, so that it has the same power to weight ratio as the 361.

I did not see or feel that much more torque running the 362. Its a matter of physics. Power is revs times torque. The revs are the same in the 361 and the 362; 14,000 max RPM. The HP of the 362 is 4.6 bph (same as the European 361). The 361 has 4.4 bhp. So do the math, and the 362 has 4.5% more torque than the US model 361. Mod a 361 muffler and you will more than make up for the power and torque difference, and pull ahead of a 362 easy. Mod a 362 muffler... no wait a minute, it is strato-charged, and does not take a muffler mod well. Oops.

I think that the 362 is a giant step backward myself. Heavier, bulkier, and more expensive. It solves problems that were and are simply not problems for me on the 361. Gas milage? Give me a break. After using a 460 or a 660, these things both sip gas. Air filter? I blow mine off with an air compressor after a day of use. So what? Takes 10 seconds, tops. The 361 saw is a great design, and I will keep all of mine, thanks. And I agree with the above post; after a full day of use, that extra 3/4 of a pound is a lot more tiring. Face it, Stihl was FORCED to make the 362, just like they are being forced to make the 211, 311, 391, and 441. And Husky is being forced to change saws like the 372. Its the EPA 2010 laws, and the EU A/V laws. They are making the best of it, but what they have come up with simply does not beat what was there before in many cases.

[Ianab]

I seem to remember all the same fuss when they changed the 360 to the 361, it was going to be the end of chainsawing as we know it. 

I dont know if the 362 is a better saw or not, but if you are worried about a few ounces, maybe be thankfull that you dont have to carry a 660 around all day 

My buddy is out cutting firewood, with a Husky 3120 and 5ft bar, and still has to walk around the log and finish the cut from the other side!

Whats a few ounces?

Ian

[STIHLFULLSKIP]

sorry,not shouting,forgot the caps thing again.  i think i you ran a 362 for a while you would like it. if we are going to run stihl saws,we dont have much choice. i still say get 20-30 tanks of fuel thru one,and then tell me it won't eat a 361 for lunch. just my 2 cents worth,nothing more. sorry if i ruffeled any feathers

[Ironmower]

Not tryin to argue, but I'd like to know how you can make more power, with less fuel??? It don't add-up.

[STIHLFULLSKIP]

the 362 is diffinately a few onces heavier,but it does have more power&torque,and will burn less fuel. these are proven facts,both on paper , and in real world useage.

[STIHLFULLSKIP]

the 362 is diffinately a few onces heavier,but it does have more power&torque,and will burn less fuel. these are proven facts,both on paper , and in real world useage. that is one of the advantages of the strato design,they are more efficiant.

[John Mc]

Not trying to argue, but I'd like to know how you can make more power, with less fuel??? It don't add-up.

If you were already using the fuel to maximum efficiency, you probably couldn't. But that's a big "if".

One obvious example would be if the timing were off. Another might be if the fuel and air were thoroughly mixed or not (this can effect flame propogation within the cylinder). Opening up a muffler is another example: this does allow the saw to burn more fuel, and gets extra power that way. However, a better breathing, less restricted saw is also better able to make use of the fuel it does burn. (One of the reasons tuned exhausts have become a popular upgrade on piston aircraft engines. With that set-up, you can get more power burning more fuel, or you can throttle back and get the same power as before burning less fuel, and running the engine cooler. I'm not enough of an engine guy to explain how this works, however.)

[John Mc]

Mod a 362 muffler... no wait a minute, it is strato-charged, and does not take a muffler mod well. Oops.

What is it about strato-charging that does not take muffler modding well? Or is it that the muffler is not as restrictive to begin with?

some guys have modded them,with decent results.(look on you tube) the 362 has a bigger muffler than the 361,but with both saws stock the 362 makes a little more noise.

Well, you can run the new Stihls. I will stick with my 044s, 026s and 361s myself. They should last for 10 more years at least.

[windthrown]

Not tryin to argue, but I'd like to know how you can make more power, with less fuel??? It don't add-up.

"In theory" the starto saws are more efficient with the strato engine design. 2-stroke engines push a lot of unburned fuel out the muffler. The strato ports inject a layer of fresh air between the exhaust gasses and the incoming fuel mix. That way the fresh air layer is pushed out the exhaust instead of fuel mix. That is what theoretically makes it more fuel efficient.

However, I have yet to see any comparisons 1:1 between the fuel use of a 361 and a 362. Stihl ads compare 'previous model saws', but not the 361 specifically. 

[windthrown]

Real world? Paper? Did you all flunk math or something? Since when is a dozen the same as a few? We are talking 3/4 of a pound here, not a few ounces. Wake up class, 12 is not a few, and 3/4 of a pound is not equivalent to a few ounces.

Also some corrections here: the 362 has more power only compared to the USA model 361. It has the exact same power as the EU/UK model 361. If you compare the power to weight ratio, the 361 is better. Stihl compensated for the added weight of the 362 with a tad more power, like they compensated for the 441. Its a gimmik to get you guys all suckered into thinking that its a souped up 361, which it is not. Its an EPA mandated saw model. Otherwise they would have never re-designed the 361, or the 440 for that matter. 

Also the Stihl ads are misleading about the fuel consumption. Thay claim that the 362 is more fuel efficient than 'previous model saws'. Case in point, they do not compare the 362 directly to the 361 fuel consumption. More gimmicks that you guys are falling for. Where 'on paper' does it say that the 362 is more fuel efficient than the 361?

So lets compare the facts please, and not the BS?

[Reddog]

Well if the 362 responds as well as the 441 to a little work it will be a good saw.

hey fella,i own them both,and run them both side by side 5-6days a week,do you??? we did not have to run these saws long to see that they cut a little faster,and use less fuel. this is no b.s,how many more facts do you want. last time i checked,you could not buy a eu,uk 361 in the us.i am not saying the 361 is a bad saw,it is a great saw,but i turn my saws every 2-3yrs. if i want a new 60cc stihl i have to run a 362. i have not had one guy complain  about the weight of 362. a 13lb saw is still a featherweight compared to a 460/660,don't you think?? this saw is very well built,and the air filtration is the best yet for a stihl.

[STIHLFULLSKIP]

put it to you this way,i will run my STOCK 362/25" against your STOCK 361/25" any day of the week.and then the facts will be clear to you.i'm not talkin' in that softwood you guys cut out there,good wood like red oak,elm,osage iron wood.that will push your good ole' 361 to the limit in both power and its ability to keep a 25" bar oiled,then you can tell how much of idiot i am for owning a 362.

i was gonna say something, but i wanted to see them "duke" it out 

[RandyMac]

Yer funny Mr. Smith.

A 361 is XL12 or 10-10 size, right? Face slappin' contests should be limited to 100cc or bigger chainsaws.

[Al_Smith]

  Oh it doesn't make a hill of beans to nothing . Big deal it uses less gas like it's a over bore 454 Chevy or something . As long as the damned things cuts and runs okay who cares ?---and yes I do a couple of 10-10 Macs that do just that but I don't get on my high horse about it .---you stir a little to the left, then to the right .

In another thread, I remember windthown saying he had tendonitis, so he liked lighter saws. I have something, don't know for sure what it is, that heavier saws hurt my wrists. Ten and twelve years ago I ran 66s and 394s, but have been going to smaller saws ever since. I wouldn't want to go any smaller than the 361, though. For some of us older guys--speaking only for myself here, wouldn't want to use the "O" word to describe anyone else--that 3/4 pound difference between the 361 and 362 is substantial.

What I've found is that my production has dropped very little if any. The bigger saws cut faster, but it only makes much difference in a big cut. So you're not gaining any time when you're walking between cuts, limbing, or lopping. I estimated once that on the kind of trees I cut, mostly hardwoods, I might save a couple of minutes in a two foot diamter tree that takes me a half hour or so from start to finish. (These are trees with a fair amount of eight foot firewood in the limbs. That's why they take that long.) But then I might gain using the smaller saw by needing fewer sit-down breaks.

I have not run a 362, so can't comment directly on that. I owned a 441 for three days, and it wasn't a bad saw, but it hurt my wrists, so I sold it and took a $200 loss. I didn't listen to the significant owner complaints...had to try it for myself, and look what happened. That's why I stayed away from the 362; had too many similarities to the 440/441 situation.

As to the 361's air cleaning...no, I don't like blowing out the filter every day, that's why I have an extra filter. Then it's cleaning every other day.

point well made,i,m not forty yet,but i can see the weight of a saw definately becoming an issue.

[stonebroke]

Just wait until you get a little older, We all seem to downsize our saws. I am looking for a rearhandle ms200. Hot little saw and very little weight. When you get older you work smarter not harder.

[NWwoodsman]

I total agree with my Northwest brother windthrown. It's like comparing a resticted,smog pump, cat, motor from the late 70's with a free flowing muscle car of the 60's. You real think you're getting more for your O'bama dollars than we got for our bush money, think again.

This forum is not the type of forum some of you may be used to frequenting. I have no idea when you say things like someone is "a joke" whether he is a buddy and you are giving him a ribbing, or if you are cutting  someone down, and since some of you are rather new, some of you may not know my rules on disrespectful conduct and comments on the Forestry Forum.  They don't happen, or you don't happen.

Now that you all understand, I expect there will be no more of it.

[bill m]

Well put Jeff. I have been noticing the same thing on other threads here with some of the newer members ( not that I am much of a veteran) if you don't subscribe to there beliefs your no good.

[beenthere]

Sometimes it is becomes a pushing and shoving match as to who thinks they know more than someone else.
It escalates just like the scraps on the street corner, or "out behind the barn".   

I try (not always successful  ) to make my comment once in a thread and then back out.   Sometimes I don't say it succinct enough the first time, and that is my fault. 

[Mark K]

I usually run a 441 or a 372 for bucking logs, we cut mainly hardwood. Would a 362 keep up with a 441. We bucked up 8500ft this afternoon in 2 hours and I was thinking a lighter saw would be nice. Most of the hard maple we bucked was 30-32" across at the base and 20" about 30-35' feet up the tree. I run full skip chains on all my saws, makes sharpening faster and keeps the rpm's up.

[NWwoodsman]

I sorry for the last post, and it won't happen again. Don't type and drink.  I got caught up in all the opinions, suprised someone didn't step in sooner with all the mudslinging going on. Also noticed it on the post about skidsteer vs tactor. Hard to know whats to far, but your right and I retract all insults. I still think the 361 is a better saw.

[windthrown]

I do not understand this myth about the PNW only having balsa wood. I have oak, apple, madrone, elm, maple and a lot of other hardwood species here, along with a lot of Doug fir. I have about 4 cords of hardwood rounds that could use carving up, actually. We also have some maples that need falling and bucking up too. Lots of wood to cut here.

Anyone wants to come by and show me how much better the 362 is over the 361 is welcome here any time. I will even provide the beer. I have lots of long bars and loops here to put on them. Better hurry though, my last stock 361 is gonna get opened up and ported real soon. I am working on a full port design to replace my DP 044 with a fully woods ported and turned down 361. I want a light high power saw with really good AV. A 30% gain should give me 5.75 HP, which is more than within typical woods porting gains. Then I will throw in a 460 HO oiler kit and be able to run 28 an 32 inch bars on it. It will suck gas and sling oil, and the EPA can... well, never mind.

I also have a line on about dozen more new 361s if anyone is interested in one of these tired old dinosaurs.

In a word? No. The 360/361/362 (60cc) series will not keep pace with the 044/440/441/372 (70cc) series saws. Especially when bucking up larger stuff (over 24 inches). I run a 361 with an 044 fairly often. You would need to fully woods port a 360/361/362 to keep up. You would also have to modify the oil pump in the 361 (or 362) to run a 28 inch or larger bar. The 361 has the same oil pump body as the 460, and you can replace the guts of the pump with the 460R parts and it will gush oil. I bought my third (or was it the fourth?) 361 barely used with a 28 inch bar on it, and it was already showing signs of bar burn, with the oil pump cranked up all the way. The 372 or 441 are probably better siuted to what you are doing.

Good point . I can't speak on the 361 but other Stihls while they may be able to handle longer bars lack the ability to properly lubricate the bar and chain .

Regarding this 362 ,it's way too new for a tight wad like me to own one . I imagine by the time it gets for me to ever own one it will be old technoligy .Fact is I've never even seen one and only one ever of the 441 .

Better hurry though, my last stock 361 is gonna get opened up and ported real soon. I am working on a full port design to replace my DP 044 with a fully woods ported and turned down 361. I want a light high power saw with really good AV. A 30% gain should give me 5.75 HP, which is more than within typical woods porting gains. Then I will throw in a 460 HO oiler kit and be able to run 28 an 32 inch bars on it. It will suck gas and sling oil, and the EPA can... well, never mind.

I also have a line on about dozen more new 361s if anyone is interested in one of these tired old dinosaurs.

would you be interrested in building a new 361/362 and selling it? as i have yet to own a modded saw.do you think a 5.75hp 361 will still be reliable? alot of people believe modded saws last longer because the breathe better,and run cooler.what is you take on this?

It depend what you doing, when going out in the woods sawing up dead trees as they lay or fall being a old fart I use my light 50cc saws that I can run all day about 90% of the time. They don't cut that much slower than my 70cc saws which wear me out in a couple of hours. If I was at a landing blocking up big wood then it would be a 70 to 90cc saw. Most of these saws with equal cc's that are well tuned are so close in cutting speed to each other that it doesn't matter.   Steve
