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.
@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.
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.
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.
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.
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.
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.
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 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.
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.
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
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.
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!
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
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.
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! 👍👍
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!!!!!!
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.

Thats why Echo is the best

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

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

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

Ok, thanks
I use my 400 a ton actually. I did exactly everything you did to yours! good little saw for sure!
I love my CS-400 for burning brush, including limbing, while working on my property.
Do it again with bar oil in it !!! I'd love to see the difference

Nice Job to open the Muffler 👍Thanks for the Video Buddy.
The muffler on the Clone 400s are wide open. But they benefit greatlyyyyy from a MM and a timing advance.
👊👽
The TW is in the house!!
Will the clone mufflers fit right on? Which company neo?
@@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.

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

I really like mine, it really shined when I stuck the Crazyfeller CS310 muffler he did on it! Is a funky exhaust exit on them.

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