C'mon now it's no fun to point out the obvious! (sarcasm)
Yeah, there I go, knocking all the fun right out of it...

Here is what I propose...Play with it. Hell, lean it out till it screams so you know what that sound is. Cut with it, blow it up if it happens. Buy another saw with a few more cc's, learn to put a killer edge on a chain, and don't treat it like the last one. It's only a ms 250. Learn on it. LOL
By porting I assume its like on a car, you match the output opening on the cylinder to the gasket and flange on the muffler so there is a smoother flow as it exits the combustion chamber?
Does anyone have a pic of their muffler mod? I intend on maybe opening up the exit hole another 1/8 of an inch from the 3/8 it is now and then maybe try leaving the screen off and cutting away or trimming back some of the lovers on the cover.
OK guys, no BS. I simply said that I have rebuilt top ends of saws and then as I stated I don't mess with carbs no knowing what I am doing and screw them up. I left that to the Stihl dealer who has the tools (tach) and the expertise to do it right. After all he is very capable and only charges $75 an hour Ha ha! But he does not charge much to do that.

I didnt read all the posts before writing this, hoping I'm not repeating too much info.
I too have a ms-250 and I opened up the muffler. To readjust the carb you'll need to remove the limiters on the H as the stock tuning is already on the limiter. I dont remember how many turns I went as I was listening for 4 stroking when out of wood. Porting the muffler really woke this little saw up. Obviously no 60+cc saw but it does well for itself. And they are right, it will make you want a 60+cc saw as I went out and bought a ms440 in need of a rebuild.
Thanks, I actually have a 044 Magnum which is really powerful but I like the light weight of the MS250 its a great limbing saw and you can swing it around all day and not get tired. What does 4 stroking sound like, I keep hearing that phrase but not sure what it means. Making a 2 stroke sound like a 4??
How did you open the muffler up and how did you go about porting it?? Smooth out the inside of the port? As for the muffler my game plan so far is drill the exit hole of the muffler from 3/8 to about 1/2" leave off the spark arrestor screen and open up the louvers a little. I don't want it to be too loud so I may be conservative at first.

Why would anyone want to make a chainsaw more powerful?
That seems silly...
For real! What a waste of time. If a stock saw can't get it done...............
Yeah! Ported saws suck
