OK SO YEAH THAT MADE A GREAT IMPROVEMENT BUT I'D REALLY HAVE LOVED IT IF YOU'D HAVE SAID WHAT YA DONE TO THE DANG MUFFLER!!

That carb needed adjusting before the muffler mod too. Ran like crap and didn't even rev hardly. So... I'm thinking "muffler mod & carb adjusted correctly" should be in the title

You should try the chain sharpening mod lol nice saw

Its so rich it runs like ass. I love the enthusiasm of the free revs.

Echo sets their saws up to run extremely lean to meet EPA guidelines. First thing you should do is punch out the muffler and remove the carb limiters. Tune it properly and your saw will last a long time.

Wow. That made a big difference!

Nice protection 😳

took the catalyst out of my cs 370 welded muffler back together tuned carb beast mode runs and cuts like a much bigger cc saw

Hi, thanks for the video. which saw earns the most with muffler mod and which wood are you cutting in the video?

Nice results !

Nice work. Do you have a link on AS to show how to do the MM and limiter trim? Thanks

More HP👍🏻 Next add cold air intake 😂

Good morning,is that the normal 14" blade that comes with the saw

Out of the box these saws are setup very rich on the high speed circuit

Can I just ask, did it make a difference, I have a new 310 and not very pleased with its performance. Just wanted to know before I hack into, not against, just asked, it’s got to cut better for me

How do you mod it..?

I think I just got video DTs from that camera shaking. :-)

I have a stihl 170. I havent used it for much but I like it

What did you do to the muffler?

Remove the cat and baffles

Can you email me a detail of the muffler mods and how you went about retuning Carb as the unleaded fuel here is Australia is crap compared to US

Nice improvement! What chain do you prefer for hardwood like Oak?

How did you "gut" the muffler?

Muffler Mods by wood cutters. I've a stock Echo Chainsaw purchased from Home Depot (?) 10 years ago. I put a new air filter in it this year. So, the Factory Settings (I have no idea how to 'adjust' the carb, etc.) are still 'factory' as is the muffler. I have changed the bar a few times and am no longer running the original chain that came with the saw. I mention all this because the saw I bought was designed by guys who could build you a carburetor and a teeny gasoline engine that would allow an novice to fell and trim (is it Buck?) a fifty foot oak, then cut it into lots of short pieces year after year without a single 'modification.' And, since the Engineers the designed these saws knew what they were doing, one needs wonder why they didn't 'MOD' their Echo's (and such) if the performance difference would have been significant? I had an old (1976?) HONDA CVCC years ago. When the Muffler 'went,' I replaced it with some generic muffler I jury-rigged to keep the sound down and was quite proud of myself! Then, it burnt a valve. In doing so, it messed up the head and a piston. Long story short, I wound up scrapping that most efficient little buggy 'cause I wanted to save the price of a 'factory spec' muffler. Turns out that the CVCC was so well tuned at the factory (met all US Pollution standards w/o any modification or catalytic converters, etc.) that the LACK of back pressure changed the dynamics and (effectively) 'blew the engine.' Maybe, had I worked designing gasoline engines, I have known that.

Anyone but the engineers that designed it should ever dare modifying it, because you blew up a cvcc in the 70s? LoL. I guess all those people running cars at 100+ mph on race tracks all around the world are fools about to blow a motor at any moment too... Or they learned how to tune.

Hey abnorm- All these saws are tuned to pass epa regulations not to perform to their peak capabilities. They will actually last longer and cut quite a bit more wood per hour being properly tuned. Oh and he is not removing the muffler only the cat. Chainsaws only require small amounts of back pressure Much less than they come choked up from the factory with.

I too respect the engineers, but I also know a well made saw can run almost twice the RPM without a problem when it's "custom built". Safety (liability) and EPA regs limit performance. PS: I see a lot of little Honda's with muffler mods that are puffing blue smoke ! IE: burnt valves !
