Muff mod on brand new saw.

[Marley5]

So like many here, I'm addicted to chainsaws and keep buying more.
Problem is I'm old I got weaker

So when I'm in the field helping my brother, he's a logger and has a sawmill, I run nothing but under 50cc saws.
He has the big pro auto tune Stihl's.

Last week he hands me a Stihl MS 250 to try, I was impressed so ran out and bought one.
It sat on my work bench looking for attention so I gave it some by removing the muffler and flogging it.
I don't care about warranty as I won't let anyone touch my saws.
Anyone else ever muffler mod a brand new saw ?

All my Stihl 044`s and MS440`s were muff modded within the first week of getting them home from the dealer. I had several new OEM mufflers to put back on if it ever came down to a warranty issue but it would be a very cold day in July before I ever took a saw back to a dealer for warranty work. I fix all of my own equipment.

That’s the first thing I do, lol
But then, I haven’t bought an actual “new” saw in years

The 250 mufflers are ridiculously restricted and the saw really wakes up with opening that sucker.
Best way is to disassemble and gut it then re-pinch it back together.
MAP torch or oxy/ac to heat up the seam…then big screwdriver.

Yes I opened up like an oyster on the half shell .
Gutted it and spun the L a little rich for awhile.
Still debating on the spark screen.

I always use a screen but replace with 1mm material. Keeps crap out.

I just got a CS-501P, and I plan on fooling with it after a few tanks. I already have a deflector for it.

That's a serious saw, hope you enjoy it.
I don't own a saw that hasn't been muff modded I can't help myself.

You'll have to remove the limiters.
The most recent saw I did " MS 250 " it leaned out to much on the low jet to hold idle.
All i needed was a quarter turn.

I ordered a better tachometer so I could tune it. I read that the cheap ones could be off a lot.

My plan is to remove the limiters, grind the tabs off, and put them back on so I can adjust the carb easier.

I don't care about the warranty. I think Echo's warranties are kind of useless anyway.
