Echo CS 400 before and after muffler mod

[@CutterCH]

My cs400 is 14 years old. I completely gutted the muffler and cut out the exhaust hole to match the cylinder exhaust port. Did that almost 10 years ago. After the muffler mod, it's a completely different saw. The 400 is a solid, durable, and very dependable saw. I've ran mine commercially for a decade, and it hasn't missed a beat. Not a single issue or failure in its 14 years.

Thats why Echo is the best

[@Make_my_day-1]

​@melonboi186 I have a husqvarna 355 Rancher and a big 460. I bought the Echo as a lighter back up for smaller jobs. But quickly found out with a good chain it hangs right with the 355 rancher.

[@davesteier-xf5lh]

Well, it is an anvil.. And chainsaw pros know not to compare their clamshells to cased saws. Theres just no fair comparison. From a Tuners perspective.. not a Talkers. Echo is top 3 brands. And your opinion is welcome. But knowing how to buy, and what.. Ill choose the big block Ferrari over the chubby under powered reliable as a Brinks truck Echos any day. Sorry. And no they dont tune better. Thats another sorry. Look through every jug before you comment back. Compare any Xp to any other “jug”. Base gasket delete your 455.. and a 455 is a 460 btw. 1/1.5mm. X 3.14… x piston mm…

[@CutterCH]

@davesteier-xf5lh Who was comparing it to a professional saw? I didn't. All I said was it's a great saw. I own 23 saws. The cs 400 is one of the 3 saws I own that are non-pro clamshell saws. The other 20 are pro saws. I've been running, working with, and repairing saws for over 30 years. I know what's what. No newbie here.

I'm a home user with 6 acres of wooded property with a lot of oak, maple, ash, and hickory. I haven't made any mods to my CS-400 (18"), but I did switch to the Versa Cut Oregon chain from the standard Advance Cut and wow, that a difference that made by itself. It cuts really nice and fast with the chain. For bigger jobs, I have a CS-600P with a 24" bar. Most of the wood I cut is between 12" and 18" diameter trunk with occasional trees pushing as high 26 inches. Between gypsy moth caterpillar outbreaks, emerald ash borer infections, and storm damage, we've been bringing in about three cord of wood a year from standing or occasional fallen dead trees for several years now. Most of the work I do with the CS-400 and I've been really impressed with it's capability given its size.

[@richhoffman432]

That inner assembly has 2 small tubes that the mounting screws pass through. These tubes keep the muffler from collapsing when you're tightening it down. I did basically the same thing you did except I came in from the back side with a hole saw and just cut the converter out.

[@williamtoney2599]

Did you split the muffler in half or just drill it out thru the existing holes?

[@richhoffman432]

@@williamtoney2599 I just went through the back cylinder side of the muffler with a hole saw. I didn't split them muffler. I found this to be the easiest way and it also retains the inner structure.

[@williamtoney2599]

Ok, thanks

[@ericfore]

It'd be a fun comparison between a ported cs-400 and your cs-4310 I wish my shindaiwa 491 had an air filter design similar to the cs-400 or 7310/4310. They seem far superior to most other chainsaw air filters.

[@aaronpowell4885]

Definitely not powerhouses but very good little saws👍🏻 IMO one of the best clamshell "homeowner" saws! Dont recall if its 3/4 or 1" but a hole saw works well to remove the catalyst in those horrid mufflers, then finish cleaning the burrs left over with a carbide like you used on the outlet.

[@CHS_sufferer]

😁👊

[@JohnDoe-ud2cc]

On mine I did a muffler mod, carb limiters, 7tooth sprocket, and upgraded to a .325 20” full chisel. It pulls that 20” through 18” of oak with no problem.

[@richhoffman432]

I'd like to see you port this and see what you can do with it.

[@davesteier-xf5lh]

There are some wicked ported 50cc saws around here somewhere like a ported 49-10 or something but i cant find it again. Like turning 28" bars. Enough to make me re think my entire collection Some on here see little saw long bar and comment they dont have a brain. Now that may be the case stumping all day. But most people arent a CLIMBER as well or know wtf it feels like to pull a saw up 3 or 4 STORIES. Me, lighter to toe up, and I can cut larger pieces and TOPS..! Without my bar coming up short.. Re read “rethinking my entire collection” I got a 261m too and theres a vid on here of a guy cutting w 28” or bigger bar Gotta base gasket delete muffler mod and timing just to get to porting tho. (Most people)

[@dubbssawshop]

The muffler on the Clone 400s are wide open. But they benefit greatlyyyyy from a MM and a timing advance.

[@aaronweatherman8423]

Will the clone mufflers fit right on? Which company neo?

[@dubbssawshop]

@@aaronweatherman8423 Farmertec makes a clone of them and Chainsaw Chainsaw 420, the red ones on ebay. The mufflers should fit right on the oem 400.

[@geneevans2600]

OK, so you're a pretty good-sized fellow who, for your applications, thinks saws around 40cc are useless & I see your point. I'm probably 30 yrs older than you (72) and at least 30 lb lighter, so my cs400 has served me well, although I did buy a cs 490 about the same time. Home Depot took $25 off the price of the 400 because I opened an account and $50 off the 490 because I opened a 2nd account. Of course, I immediately paid them off and started enjoying my cs400. It has been an excellent performer for me! If it were any better, I wouldn't be able to keep up splitting mainly red & white oak and hickory. Cutting, hauling, splitting & stacking by myself. My 19:18 saws are just right - don't want to overdo it. BTW, you kinda favor Blake Shelton.

[@tedneitzel]

I use my 400 a ton actually. I did exactly everything you did to yours! good little saw for sure!

[@steelcityperformancesaws]

great video, dealing with those catalyst type mufflers isn't easy.. Just a tip they no longer make MAPP gas (since 08) which burns at 5300F. what your using now is called map-pro which only burns at 3700F. 100F over propane at 3600F. Very little difference for three times the price. I bought that map-pro for years until I was aware of the difference. Here in Canada the yellow bottle is $23 and propane is $7. hope this helps

[@novicelumberjack]

I had no idea, thanks!

[@DanielJohnson-ps4xv]

I’ve got an echo cs400 and an old 029 farm boss I bought in 1999. Day and night power difference. It also goes the other way on how much easier the cs400 is to carry around.

[@w6qd]

I love my CS-400 for burning brush, including limbing, while working on my property.

[@jonathanhoekstra6174]

I agree with you on the idea of a saw that small. Bought a 120 Husky for only one use, limbing after the tree is down. Easier for me to wade through the tangled limbs with a small saw. Other than that I use 60 cc and up to fall and buck.

[@Ridefastorgetpassed]

Do it again with bar oil in it !!! I'd love to see the difference

[@LordofTreasure]

Nice Job to open the Muffler 👍Thanks for the Video Buddy.

[@z1berzerker]

I picked up the Chinese clone from V modest for 100 bucks... it has standard cylinder and muff. Echo does seem to make a more solid saw. Either one be great saw to pack around light weight and got some rip

[@kraftzion]

I just did an ignition advance on a echo cs3000. Before the igntiton advance I have a qztodo 2500 zenoah clone that would beat it. Now the echo smokes it, not even close. 13800 free rev, 12400 in the cut. Its a 2005 saw, I think a lot of the older echos could benefit from an ignition advance.

[@bradr8806]

lol, I use the shit out of mine, drilled a couple holes in the muffler, 18in bar, keep it sharp, keep oil in it, cuts great, light, runs great

[@jamiewykes8585]

I wonder how much faster it will cut with the chain adjusted and getting oil? That might be a interesting comparison. No other changes

[@luapmckeever721]

This is me cutting wood my whole life and about 10 years with a cs400 and wondering why you shut it off like that...

[@jimmylarge1148]

I wonder why they pull the cord a lil when turning it off?

[@davesteier-xf5lh]

Uhhh… cant guess why.. My guess us its at TDC and ready to fire. Or the vac pulse is primed for next i dont know..

[@JorgeVonVogler]

You must hate Sthil ms170 I actually was cutting small tree down. With em np. Looking to upgrade to this echo cs400

[@joelhockett8137]

Keep it! When you turn 60 try it out again. I use a cs370 16" mildly modded for most everything under 24" or so, b4 I'll use a bigger saw. I can fell and buck a 24"(rock hard) yellow locust standing dead 60ft tall split 6 of the biggest rounds and loaded In about 20mins. If, i used my 620 I'd have to rest 10min. after the bucking? All im saying is, I can get more work done faster without a heavy saw wearing me down. I always thought these smaller saws were kinda worthless also until now!

[@derpherpp3]

Is this goes for all Muffler mods?

[@keystoneridge]

Pleeease port that! There's a lot of 400s on the used market for very cheap and I've always wondered how they'd perform with a port. Thx

[@AndreasBrOlesen]

Hey Boedy I’m from Denmark and own a small Echo CS-350WES (among many other saws). It is a small, pro grade, 36cc chainsaw with a horizontal cylinder, so very compact. I’m very fond of mine. It is so light and it feels like it really wants to do work. Do you have those where you live? If so I really recommend you try one. The new model is called CS-362WES, but I’m not sure of the differences between them. The TES version is a top handle, but otherwise same saw.

Never owned a 310 yet. Wander if a 400 engine could be fit in one🤔😅

​@@aaronpowell4885I feel your pain AP

[@mrmojorisen6336]

keep it! this saw is like a Glock (gen2-3), it goes bang 99% of the time. get rid of the safety bar and chain, put the WOODLANDPRO 16" ARBORMAX BAR 3/8LP X .050 X 56 DL, add a semi or full chisel chain and do work! its not a pro saw, but its a damn good reliable saw for lightweight work. i own, Tacoma truck, made in Japan. Kubota diesel tractor, made in Japan. Echo (X3) chainsaws, a weed-eater and blower, all made in Japan. all have been problem free just regular maintenance. note: the cs-400 engine is made in Japan and assembled in the US. no doubt the Swiss and Germans make great products, but the Japanese just make damn good reliable products! 👍👍

[@stevenstovall9668]

Put you an OREGON 91VXL062G chain on that thing and it will greatly improve the performance. I couldn't believe how much of a difference it made on my CS-400. The safety chains that come on them from the factory suck!!!!!!

[@toddwatzka960]

Mapp Pro torch only gets 130 degrees hotter than a propane torch. Not really worthwhile. In my opinion

[@novicelumberjack]

Clearly, you've never been stuck trying to braze silfos with propane. That extra 130º makes a world of difference when needed. It's the difference between getting the job done, and not.
