No big deal.

I run a modded 044. I got the dual port muffler from Stihl for $32 and bolted it on, tweeked the carb and that was it. Runs like a raped ape on steroids now. Before it just ran like a raped ape.

I modded the 290 as well (drilled some holes), but I put the stock muffler on before I took it back to the ex's place. I sold the modded muffler to a guy on AS. I also modded my 250. Easy to do; open the shark gills on the muffler and tweek the carb.

I got a Wojo job on my 44 ... pretty good, made a video.

Few weeks back out on TransGrid, I was cutting with the 371xp after finishing with the 372xp... Tell ya what! The bolts vibrated off from the muffler that holds it on the engine, it probably amped up 20db in noise and it was running like a raped ape on steroids (nice one windthrown!) after that...

Thats cuz you live in "Dead Stick" Florida...

Running a saw without a muffler will make it sound like its cutting like a bugger, but you have actually lost power. A saw needs a certain ammount of back pressure to get max power. Stick a tuned exhaust pipe on it and you will be amazed. You want a simple muffler mod ,do what loggers did for years, take your scrench and stab 6 holes in the mufflers front cover.
Just a word of advice for you residential tree removal guys. A noisy muffler modded saw might be great in the back 40 cutting firewood, at a timbersport chainsaw competiton or in the bush logging, but I learned from doing residential tree removal with my dual ported muffler Stihl 066 years back, that I was scaring away potential customers. I actually had to block off the one outlet to quiet it down because so many neighbors were turned off from the noise.
My MS 200 Stihl, 346,372,395XPs Huskies run just fine on factory quiet mufflers ,I just make sure my airfilter is always clean and my chain is always razor sharp and give it a quick touchup with the file to keep it there if needed. The clients neighbors aren't pissed off and they are giving me lots of extra business, kind of like a domino effect. No modded mufflers for me.

all the old homolites the mufflers just rusted out fell off. there is a lot more than meets the eye with that o'l 066er. the q port is far too big to run on a stock saw. she's lucky to get 5 mins per tank/ stump and kicks like a mule
this saw snaps chains, smokes clutches, and explodes rim sprockets like a bad habit. its best to use a full race fire suit and a motorcycle helmet when flushing stumps cause one day she's gonna BLOW

I'll punch out the baffle when its gets clogged that helps , but it cuts the back pressure way back, and they will flood easier.

What in the World Happened back in the Day of running like a McCulloch
1-10, Mac 10-10 Auto, Pro Mac 60 or Pro Mac 700 . Compared to Those Chain Saws, the Ones Today are like a Whisper. . Up until Last Fall, that was all I had run was the McCulloch Models that I have just Mentioned, and What a Difference in the Noise, even with my Mufflers Modified on my 044, 034, and 024 .
When I was in my Teens, I used to Cut Fire Wood for farmers. One of my Customers, that I was cutting for, his Bush was in a Ra vein, and between his Buildings was Rolling Hills.
He could hear my Pro Mac 60, from the House, but not my Homelite XL-76. One time, he didn't hear my Chain Saw for Quite a while, I just happened to look up the Lane, as I was Bucking with my Homelite, I saw him Racing down the Lane Towards me, with his Pickup Truck.
He was Concerned that something had Happened to me, or his Young Sons, that where at the Bush watching me Cut up the Trees into Fire Wood, because he couldn't hear the other Chain Saw. Bruce.

Yes Bruce people today are more critical about noise. Today there are more seniors then ever and the tree service industry will get even busier because of these aging baby boomers. And they have money [good pensions] to spend. But I remember a few years back when I pulled that noisey 066 dual port out my customer's neighbors scattered giving me the impression they didn't want me in their yard. Some of them hired another outfit to do their work. Timid little old ladies are one of my common customers.
When I plugged up the 066's muffler I noticed the quieter saw spent less time at the gas can fueling up and she still has an abundance of power. I can hear warnings of danger better over the quieter saw also.

Bruce Hopf

Man Oh Man. I guess the Next thing, we will be going Back in Time to the of Buck and Cross Cut Saws, because People don't like a little Noise. happy097:. Bruce.

Actually that is very true. Last year I deadwood pruned a boulevard of old American elms next to a hospital. The contract stipulated "no gas powered chainsaws,hand saws only". Man my right arm never worked so hard.

Therrin

How about electric chain saws??

I hate the things, but if you had to do a whole boulevard, there's that.


LOL!!! Get a gasoline generator to run your electric saws. Then when they complain you can say "There are no gas powered saws out here"

Willard Holmen

I'm afraid that would not be a good idea Therrin. Seeing I had to roam all over those tree's canopy with a climbing line. Its bad enough redirecting a climbing line let alone an extenstion cord. My Silky Sugoi handsaw and Hayauchi polesaw are kickass. Alot of pruning jobs thats all I use and don't bother hauling the MS200 up there.

Therrin

Yeah it wasn't too serious. I've been given all these electric saws and I don't have any excuse to use them for anything. I've got 4 of em now. They work perfectly fine.... just not much use to me.
I'm gonna give them to my church.

Electric ones scare me actually.... apparently their clutches don't jam up with the chainsaw chap's material the way gas saws do. Something about too much....torch? Can anyone verify this?

Therrin

Was over at my new saw shop the other day hemming and hawwing with the owner there, gettin to be buddies. We were totally on the same level and my dad was standing there completely in the dark. I almost felt bad for him till I remembered being in that place in my childhood and then I just smiled to myself. =)

Anyhow, I asked him if many people bring in ported or modded saws....

OOh.... that let loose his spiel on how bad they are for your saw, overheating problems, spark and fire problems, etc etc etc. I suppose for the sake of his business and liability that's the response he's gotta give, but he didnt seem to keen on them.

How much validity is there to the saw running hotter with modded mufflers?
Hot enough for it to do damage or decrease the life of the engine?

Willard Holmen

I'm all for modded saws. All the big saw companys do their product research and development through the end users in the pro market. And most pros mod their saws for peak performance because they are usually on a piecework pay scale.
Years back [1982] I would buy a new saw from a reputable dealer have him up the compression, take 2mm[80 thou."] off the piston intake skirt, groove in some finger ports and open up the muffler. I could drop trees like crazy.
Just modding the muffler won't make more heat [ heat gets out faster right?] Its when you increase the compression and fuel/air intake is when more heat is generated.
Modded saws just don't fit in my tree business now, I'm no longer in the bush and I found loud saws in urban tree removal scares away business. Just pulling the spark arrester screen out of my MS200 top handle is enough mods for me.

Hello Charlie,
You are from Moravia. What do you do in the Czech Republic?

joemag

i have an 026 and 2 015s that i want to open the mufflers on. how much should i open them? is it based on the amount of exhaust port volume in the jug?


as for therrin's question about the clutches on the electric saws, i have a homelite, and it does'nt have a clutch on it. the sprocket attaches direct to the motors shaft.

Therrin

That's probably what I meant... in my ignorance.

That they DONT have a clutch maybe? (do they? i dunno)

The fact being that they tend to tear right into chainsaw protective materials and keep on chewing. Mmm, maybe that's it, cuz there's no clutch to jam up?

joemag

i don't use the 1 i have. my wife has used it around the yard a few times for bushes & small limbs. i help someone move and they gave it 2 me. it was rusty and would'nt turn so i took it apart and cleaned it up 4 her.

(WLL)

Electric is slow but extremely powerful, they have gobs of torque. Its very hard to stop the chain; doing so will burn out the motor. I'm not sure if the newer electric chainsaws are still direct drive, i would think they are probably still the same, its hard to use a centrifugal clutch without lots of rpm's

General rule of thumb is maximum size of exhaust outlet of muffler not to be no more then 80% of size of exhaust port. Some mufflers have baffle cones ,remove that too. But make sure to make up and install a new spark arrester screen on the new larger outlet.

Bruce Hopf

For your Muffler for the 026, what I did with my 024, was I tore off the Front off the Face Plate of the Muffler, and I took the Guts out of the Inside of the Face Plate. I Mig Welded a Piece of Metal, placed in the Inside of the Face Plate, and Welded Beads of Weld to cover the Rectangle Hole in the Face Plate.
I then Drilled a 5/16" Hole in one of the Four Corners of the Face Plate. As for the Muffler, part that Attaches to the Motor, I just removed the Baffled, by Drilling out the Screen of the Baffle. That is all I did.
Now if you wanted to be Fancy, Place a Clutch Bearing Cage, that has been cut in Half, and Tack the Pieces into place. I just left the Holes the way they came out of the Drill Press. Bruce.
