The Taliban run stock saws



No flame from me!I know that it makes me sounds boring,
And it could get me ostracized on a fan site like this.
But it's an election year, so a good time for all opinions to be heard.
Anybody else satisfied with stock chainsaws? Happy if they start and run the way that STIHL or Husqvarna (or other) engineers intended them to? I never heard of 'modded' saws until frequenting sites like this. And a few have been fun to try at GTG's. But I have had plenty of frustration with saws that wold not start, or were dirty, or poorly maintained. So give me a clean, well maintained saw that starts, runs, and has a sharp chain, and I am probably going to be a happy camper.

^-^-^ THAT ^-^-^The best modification you can make to a chainsaw is a properly sharpened chain.
21 years of tree work without ported saws. Muffler mods only and a few with a timing advance.
Somebody else resurrected this post, but I am still curious about some information I was recently presented with.
Let me start off by saying that I know nothing about how a motor is put together.
But.... I was recently told that if you do not have the air intake and output, balanced; that you get a weaker saw. I guess to my thinking I am not sure about this statement and would love some more informed input. Especially concerning the "just muffler modded" side of things.
The biggest restriction on most chainsaws, (due to the EPA) is the muffler. They want to trap the heat to burn all the fuel, even though it hurts performance and the life of the saw, so generally that is the easiest mod to improve performance.
Once you open up the exhaust, if you then add a less restrictive intake (like a Max Flow or even a HD-2 on a Stihl) you further improve the flow of air/fuel in and out of the saw. As this improves, a timing advance will help to keep everything in sync. If you get it right (and the information on these websites helps a lot with that) you can often get a very noticeable improvement in performance w/o even porting your saw, and porting can improve things even further.
It is very similar to what we always used to do to the cars (before electronics). You would add headers & low restriction mufflers, a K&N air filter, then advance the timing to make it all function correctly. You would feel the difference immediately, and often get better gas mileage also. We also used to install steel shim head gaskets to bump up compression, similar to a base gasket delete.
I suspect that although your saw may consume fuel a little faster with these mods, that you will be able to cut more wood on a tank of fuel (something the EPA regs fail to take into consideration). They only measure emissions output for each size saw, not productivity.
I hate the HD 2. I'd rather use the cheap $10 filter from HL supply if I don't have a max flow.So what about the newer saws that come with the HD-2 ?
The same source of information pointed out that instead of upgrading to the Maxflow (which I have/had done) I could simply have washed the HD-2 that came with my saw, and or gotten a second HD-2 and washed them in rotation.
AND regarding the timing advance etc. Wouldn't a M-tronic saw automatically adjust the timing?
Just mean a worksaw, l have some old shelf queens, some NOS in box saws, some older saws that are cool saws but to heavy and vibrate too much, a modified saw for fun and the rest get used daily for work. Some worksaws are ported and modded, most are near stock. One of my most impressive saws is bone stock and will outcut similar displacement modded saws....the 681 Solo I have had since 2009. One saw I use a lot is a T/H 23cc makita 231t its the lightest gas saw on the market but N/A in the US...2.5kg with b/c!
I think you have to get into cylinder work of some sort to call a saw "Ported" IMOWhat dictates ported? A 550 and 562 run dang good with just a MM
Ive seen very few cylinders Ive been into yet that couldnt benefit from casting flaws removed and ports squared a bit to improve flow?I think you have to get into cylinder work of some sort to call a saw "Ported" IMO
I tend to think of all the other useful stuff we can do to saws as "Modifying"
