Thanks redpowerd, I prolly do deserve some sort of punishment for being such a windbag, just trying to get everyone on the same page.

LMFAO Russ! Never at a loss for words, I see. Good to know you haven't lost your vocabulary skills.

One minor point- There are guys who modify chainsaws for a living and they are very good at what they do. I do not even pretend to understand what Danny Henry does to an engine, but I trust his ability and skill enough to know that he will find and correct any defect in my chainsaw engine. Therefore when he sends me back my saw, it has no defects for which I might need warranty work. Danny has already found and corrected any defects. If my saw breaks, it's most likely from me screwing it up and not a warranty item anyway. I'm using a modified 346XP (46cc, 18" bar, 10 lbs) on a daily basis and it will keep up with a Stihl 044 (72cc, 16 lbs) on anything below 20" diameter. I've been running this saw for over 8 months now and it blows away anything remotely close to it's size. If it blew up tomorrow (highly unlikely to impossible), I'd buy another one without hesitation. Modified saws make me a lot more money than stock saws, are easier to use and run cooler.

 Thanks for the kind words. Most of the people on this site never had a ported saw in there hands. They have no idea how a saw should run.
 Shoot me an email and tell me what you did at the other place.
Later

We if it's any consolation I ordered a Walker muffler for my 066.

[Minnesota_boy]

I really would love to modify my Stihl MS-180 to at least open up the muffler more, but the one thing I keep reading is that you should also richen the high speed mixture a little.  Makes good sense, but the carburetor on this little gem has fixed jets on both idle and high speed.  Guess I should be satisfied with only removing the spark arrestor screen.  That alone increased the power, made it idle better and the top RPM went up considerably.  All achieved by removing two nuts holding the cover on the muffler and lifting the cover off, taking the screen out and putting the cover back on tightly.

Hi Mini soda Boy,

I hope that your rpms didn`t increase too much, that`s a sign of leaner running as well as less restriction. I`m not familiar with the carb on the 180 but is it possible that it has a replaceable jet inside? You might also get away with fattening it up by opening the lo screw a little more or bending the metering lever a tiny bit. If you aren`t intimately familiar with what I`m talking about, I don`t want to encourage you to try any of this and risk damaging your saw. Can your dealer help you out?

The dealer just closed down.  I'm not worried about the RPM's as it is, I just don't want to lean it out any more by letting it breathe better.  I know what you mean about the metering lever, but I don't want to change that as it has to idle for long periods and that change might cause it to load up, which would defeat the purpose. It does what I bought it for and it does it quite well, so I think I best leave it as is.  I just wanted to mention that just a minor thing like removing the slight obstruction of the spark arrestor (not needed, I use this almost exclusively when the ground is snow covered) can make a fairly big change in the performance of a rather small saw.  By the way, when I said that is had no mixture screws, I meant none.  The only adjustment is the idle speed.

Dont you just hate it when theres no adjusting screws on the carb? I have seen such models of carb on the FS75 and FC75 model trimmer and edger, and I DO NOT like not being able to adjust the mixture settings. But sine the MS180 is a homeowner type saw, I guess the reason for not having the screws is so that some guy that has no idea what hes doing doesnt touch the screws and ruin his saw. No offense to anyone who doesnt know how to tune carbs. I may send my saw to Dozerdan soon for some engine mods, As is my saw will match a stihl 044 in anything under 20" I just want more power from my saw.

russ, u bend that lever, u risk the saw with higher rpms?

Depends on which way you bend it. I was thinking that MB could bend it ever so slightly, and I mean a tiny bit up, which would richen the fuel/air thus decreasing unloaded rpm. Being bent up keeps the needle off the seat.

What happened at Eagle River ?
Well for a guy only running a alcohol saw the second time in his life < Cecil Star> and that was the first time he cut with it this year , i think he did very well , at least he didnot blow it up and it came home in one piece.
Cliff you should know that Cecil is just starting out and is scared of these saws and that is the way i want him to be plus his cold start is not much yet so he is giving up alot of time there, his cold start at Eagle River was 1.79 seconds so there is .8 or .9 of a second there a lone plus he does not know how much to push yet but give him this year to learn and we will see how he is doing

I just did my first modification: installed a Walker mufler on my 346xp.  Immediately I noticed two things: more power and more torque at lesss rpm's .   This saw runs really runs smoother and more consistent now.      As Rocky said, if all you are worried about is mfg warranty, then just stay with what you get in the box.   And for those who want to move up one or two sizes to avoid a little mod, just keep in mind that you will need to carry more pounds.  My 346xp is only 10.6 lbs; not 12, not 13 .    Bob.

If those stuffed up mufflers were so good for the saws, don't you think the saw manufacturers would sell them worldwide? Why do you think the USA gets 'special' mufflers with tiny outlets, and smaller carbs? It isn't to promote longer engine life, that's for DanG sure.

[rahtreelimbs]

A modified saw is only as good as the service/follow up after the saw has been modified. In this arena Dan Henry is the man to deal with. I talk with Dan quite a bit and he has always found the time to answer any questions ( there are a lot of them ) that I may have. Dan is as standup as they come!!! ;)
