Ok, I realize I'm getting overly pedantic about this...
Pedantic is not an appropriate word for an arborist site but maybe I’m just being too concerned.

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

I looked at the two saws' service info specs
Both saws share the same stroke,
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.

If you go to the stihl site and look at the ms250 it has quite a bit more power than the smaller bore version. The MS250 is a 45cc saw, so should make more power than the 36cc and 40cc Echos. IIRC, it doesn't have a fully adjustable carb. I would buy a CS450 before I would buy a MS250
Have you seen the thread of the insides of the new top handle cs-355t? Might make one want to wait and see if the rear handle saws get similar treatment.I think the new CS352 is the rear handle version of the 355t.
I would be confident the smaller one of these two will pull a six tooth sprocket just fine.even the Echo CS300/301/305/306 30cc reed valve engines pulled a 6T 3/8 low pro spur sprocket

same size engine as the cs310 rear handle, way way more power. the little cs310 is the only saw in the echo echo line-up i tell people to stay away from. g u t l e s s.
brokenbudget; same size engine as the cs310 rear handle said:CS310 and CS352 have same spec weight at 8.8#, but 34cc vs 30.5cc. The 355T has 35.8cc and 8#.

I have a 400 and 250 and the 400 cuts just as fast with a vx chain.

Point 1 was meant to compare two stihl saws with the same stroke as this thread 32mm and bores of 40 and 42.5 and the resulting differing power rating of 2.5 and 3.0 hp. 1.9 and 2.2 kw doesn't seem as impressive though. I am pretty sure the stihl one can be set up with a rim sprocket of seven tooth low profile.
Point 2 I think redshift42 likes longer strokes and the stuffed crank essentially closed port modern design still has a shorter stroke than these ones being discussed.
Point 3 exactly what diameter the carb forward case reed top handle can pull a six tooth just fine might be up for some discussion.
CS310 and CS352 have same spec weight at 8.8#, but 34cc vs 30.5cc. The 355T has 35.8cc and 8#.
In hindsight I agree. It's a cry for help-- after being a stay-at-home dad for the past many months I'm overcompensating when trying to remember how grown-ups really talk.Pedantic is not an appropriate word for an arborist site but maybe I’m just being too concerned.
Well yeah ...then again, I need to run a 370 too.Sounds like you need to run a muff modded CS400, A guy at a saw job was using a MS250 to cut up slab wood as I sawed it and I let him use my muff modded CS400, the MS250 didn't get started again... Steve
At the risk of running way off topic here, I just couldn't not comment on this......the little cs310 is the only saw in the echo echo line-up i tell people to stay away from. g u t l e s s.

My 370 was a HD clearance find, just a stripped powerhead; slowly I'm sourcing each replacement bit as I can find them cheaply enough to maintain the "what-a-great-deal!" status. For now I'm left to imagine how it'll run.
That's why I admitted to being pedantic about this. Internet forums are rich with guys lacking real-world experience while spouting/touting theoreticals as gospel-- I tried to not be That Guy. I was just hoping to hear some discussion about output & personality of these "same but different" engines. It's cool to compare the theoretical against the experience of those who've actually run the saws. (Tho' I'm a little disappointed w/ the results)

I wonder if you had experience w/ a bum cs310, BrokenBudget. Last month I picked up one of these at a garage sale b/c it's price & condition was just too good to leave behind. I figured on flipping it on CL the next day, but after running it I'm having a hard time letting it go. There's now a half cord of 3-8" birch & alder in my driveway and I'd definitely not call the 310 gutless. It digs in and just plain cuts in a way surpassing what I'd expect from 30cc's (in fairness, I've replaced the chain). I keep reaching for the darn thing and the 026 is getting jealous.
With its displacement & compression advantage I'm sure the sibling cs352 kicks butt by comparison (probably even giving the cs370 a run for its money!), but I would not hesitate to recommend the little 310, especially given its price advantage.
