The 435 is a nice saw, ran mine yesterday to finish up 5 hard Maple tops. Very fuel efficient, it never did consume a tank of fuel and I cut quite a bit of wood with it. It's a stratto-charged engine, and has very good power for the cc's. It's faster than the CS-400 in chain speed and cutting power. The CS-400 I tested it against was stone stock and right out of the box with only the limiter caps removed and carb tuned.

Pretty much a toss-up, either one would be more than enough saw for what he wants. The Echo has a better warrantee, but to date I've owned several dozen Echo products and only had one issue with a CS-510 that was missing the tank filter, which I correct myself in minutes. Never owned or ran an MS-211, they have a good reputation as well.......Cliff
 
Thanks.

I have owned Echo and still do, trimmers, 3000, 330t, both not here, but over 15 years never had an issue with Echo. Other than the poor chains to begin with.

Does the 435 feel more like a larger saw than it is? And which saw sounds more like a "chainsaw of yesterday?" The mufflered down saws sounds different and the "tinny" sound of some Stratos saws, like the MS211 or MS362 I find annoying. I'm the one that will work on his if there is any problems aside from warranty.

So far he don't want to mod anything, just keep the saw bone stock. If I can get him onto this site CAD may change that in a hurry!

:cheers:
 
The 435 is strong for 41cc, and loves to rev. The Echo CS-370's and 400's are slower engines, with broad/flat power curves. They "grunt" quite well for the cc's. Choosing a 435 or a CS-400 is nickles and dimes, either one easily fits the task it's being purchased for.....Cliff
 
On the CS400 the fast idle comes on when the choke is pulled, just another plus over the CS370. Owning both I wouldn't even consider the CS370, lots more power with the CS400. Both will be built better than a Husky 435 with a metal front handle , 300 hour EPA rating, metal oiler, metal inserts where needed and you wont find a better handling saw. Steve
 
I own an Echo cs 400 and I love this little saw. I bought mine to take down a small maple that was to close to my pool. When I first used it I was not impressed it did not have the power that I had hoped it would. But after a few tanks of fuel and removing the cat and opening up the muffler it became a much stronger saw. I also put a 16 inch bar and chain on it and richened up the carb. I like this saw because of the ease with which it starts 2 pulls cold 1 pull warm every time. get rid of the safety chain that it comes with and get the stihl 3/8 picco and you will be very happy with that saw.
 
Don't shy away from a CS-370 for a couple cc difference. Muffler modded one will easily outcut a stock CS-400 with the carb set correctly. Had one of my CS-370's out yesterday, cross-cutting some pretty knotty material on the woodpile so it would fit in the wood burner. Amazing how much grunt those little saws have for the cc's.

It's a saw that you really start liking after you've had it for a while. Not overly impressive for rpms or high chain speeds, but they dead solid reliable, nice features, including an adjustable oiler, and dirt cheap if you have some patience with E-bay auctions......Cliff
 
I grabbed both of mine up basically in new condition for just over $100 each. A couple cc's difference is easily made up with a muffler mod and good tune. It also takes more power to run the 16" bar. A CS-370 with a 14" bar is pretty much on par with a CS-400 and 16" bar for the type of work those saws are used for.

When I did timed cutting with them, I left the longer 16" bar on the CS-400. I don't remember the specifics of the testing, and my old hard drive crashed a long time ago, but the CS-370 was quite a bit faster than the stock CS-400 in the Cherry log we tested them in. Nearly as I can remember, the log was apprx 12-13" in diameter, and for three cuts the CS-370 was apprx 7 seconds faster every time......Cliff
 
I have a new ms 390 and a cs 370 with major muffler mods with a good tune and the echo will out cut the 64cc stihl both with good chains. I got echo new for 100 is only reason I got it I thought they were junk. Imho its best saw I've ever used and wouldn't trade it for the world.

I am also the owner of an MS 390 and an Echo CS370. I think the CS370 is great for what it's designed for. But it's the MS390 that wears the 24" bar and makes short work of my oak scores. The CS370 just stays in the shed fapping, for the most part. If i'm scrounging, it's MS390 for me. :mad:

If the 65cc MS390 doesn't cut faster than the 35 cc CS370 theres something wrong with the MS390. If you haven't modded the muff or tuned it richer on your CS370 do so, it makes it a whole different saw. Steve

Cliff the thing is that a muff modded CS400 cuts way faster than a muff modded CS370, also I drill a couple extra 5/16 holes out the front and redesign the exit cover. Just making the stock exit a bit bigger might not be open enough for best performance. Steve
 
I've modded several of them, and evaluated them after opening up the exhaust exit hole, with and without the deflector in place, etc. All you get is more noise beyond opening up the 4 holes in the "can" that held the catalyst and opening up the actual exit hole about 30 percent. No detectable difference with out without the deflector in place.

Removing the catalyst is the big wake up call for them, that mod alone increases their power significantly over stock, at least based on the few I've modded here.....Cliff
 
Will My NEW CS400 run lean Stock!!

Ive been reading alot about the Echo CS-400 running lean from the factory and after just ordering one I would like to know what carb setting need to be checked or changed before I run the aw much, my brother has owned his for around a year now and loves it. Iam new here so any help would be much appreciated, Thank You Daniel
 
cs500 p

i want the 500 its right around the same weight as the 400 and ive read nothing but good things... i think it will be my next new saw.... same weight more or less then the 400 and way more power... what ya all fellows think??? money is not a problem.....those 500s look real nice......

Yes mine was very lean from the factory. I ran it for maybe 5 minutes than pulled the caps and richened it up on the high side. It was so lean I was scared it would seize at any time.

Ok, I realize I'm getting overly pedantic about this...

I looked at the two saws' service info specs and noticed the CS370 and CS400 have a few interesting differences.
Most notably, the little 370 has considerably higher compression than the 400. While the bigger 400 has an 11% displacement advantage, the little 370 trumps the other's compression by 17% (148 vs 127psi).

Both saws share the same stroke, so the 400 achieves it's add'l 3.9cc's w/ a larger bore. My understanding of engines is that the more oversquare (bore exceeding stroke) they get, the more "peaky" the power delivery with midrange grunt compromised, suggesting the smaller-bore engine could find a sweeter spot when the revs drop in the cut. (The 370 is spec'ed at 400rpm higher WOT speed, tho').

So I'm interested to hear from anyone who's run identically set-up/modded CS370's and CS400's back-to-back and can comment on their respective personality & power delivery. Mountainlake said the 400 has lots more power, which surprises me. Sure, there's no replacement for displacement but, given its other on-paper advantages, shouldn't the 370 hold its own in actual usage? I'd expect the little guy would have a certain snarl that its big brother lacks.

I got a CS-400 about a year ago for 60 bucks with a bad clutch. I replaced the clutch and the saws been a great little saw. One guy always picks it up over the 142 Husky and 345 Husky i got.
 
In timed cuts my muffler modded CS-370 was faster than a stock CS-400, both correctly tuned. The CS-400 was toting more bar, 16", vs the 14" on the CS-370, so that alone make them closer without any other changes.

I use my CS-370 at least twice a week here, and haven't yet been able to find a flaw in it's armor anyplace. They are a great bargain in a small limbing saw....IMHO.....Cliff
