600P mods
Any info on 600P mods, I guess I can clean the muffler out like on the 400, right?

Yeah ok, I admit I was being optimistic when I made that statement quite some time ago. I was comparing the performance of my flowbenched CS-400 muffler to a........Husky 55 Rancher. And I had a Stihl Picco Chain on it, not the Oregon 91VX I have now (which is much better chain for the saw). Still, the mods which are totally external to the engine itself, made a HUGE improvement.
If you liked the flowbench data, wait till you see what I have brewing for modifying my Echo String trimmer
. Also cuts way faster than my CS440 45cc Steve
couldn't get that through a friends head the other day:hmm3grin2orange: buddy had a very good running 440, i told him the cs 400 was a faster saw. he said nope more cc's in the 440 so it has to be faster and stronnger. i smile and toss him the 400. long story short, he bought one today and traded the 440 in on it:hmm3grin2orange: i gotta do a muffler mod on it tomorrow to keep him quiet, otherwise i'll have to listen to him whine that his saw taint as fast as mine.
yes, both my cs400 and (used to be) his 440 are muffler modded, the 400 is just faster everywhere. mind you, has anybody tried low pro on the 440? has anybody tried .325 on the 400? wondering if that may be the reason the 440 is coming up slower than the 400......
all i've ever owned has been echo...with that said i had an old 500 that had a recall on it from like 1984. if your serial #'s were between so and so take it to your dealier and walk out with a new 50cc saw. Even though that thing ran great i thought what the heck took it in and paid the difference between the 50cc and jumped up the the 680. great saw in my opion i've ran buddies sthils and to be honest i perfer the 680 not to mention the warrenty...alot of guys are sayin the warrenty isnt worth the paper its printed on well for some reason my first 680 had a leak somewhere in the piston and sized up took it back to the dealier and walked out with a new 680..
so as for warrenty i've had great luck...I normally run a 24" bar but i also have a 32" bar with a skip chain and a reg. chain for it not the fastest but she'll pull it...i'm rebuilding a 064...haha cant wait to see what that thing will do...bought it for 35 by the time the complete rebuild is done i'll have bout $250 into er...and that will be my first experence owning a sthil...But as for echo's i'm a believer...Hoogie
I owned a CS-440 for a while, and it wasn't impressive anyplace. I also owned three Husqvarna 55 Ranchers (open port), and they were also pretty lame, at least in comparison to a closed port model. You will notice that the open port 55's and CS-440 are no longer in my line-up.
I would NOT recomend going up to .325 on a CS-370 or 400. They cut fast because they are set up with 3/8" LP. They don't have the power it takes to effectively run .325". Just going from a 14" to 16" bar slows one down some. I've found they work best with the 14" bar and 3/8" LP set-up.....Cliff
I've been an Echo fan for the past 5 years and have the cs330, 400, 450, 600, and stand by them pound for pound fine saws. I also sharpen a mean chain. Anyway I've been reading about muffler mods and reading and reading but never trying one. The other day I was sitting in the shop, looked over at my little climbing saw that I've had for at least 5 years, and said its time. I removed the muffler, grabbed the drill and started to drill it out the cat. After getting all the cat removed I started drilling holes in the ring that held the cat. I removed the deflector, spark arrest screen and drilled two 1/2" holes under the deflector cover, enlarging my exhaust outlet. All I can saw is wow can't believe the difference, night and day, just by doing a 10 minute alteration to the muffler.
