I love a fun post!!! :D

Thanks guys.
Things are a little strange with the saw & original story.  Got it home & it actually feels like it has pretty fair compression.  Haven't stuck a guage on it.  Saw looks nice.  I assumed it was straight gassed but no idea really.  pulled the muffler & plug & what I can see doesn't look bad.  Little irregularity in top edge of piston right at exhaust port.  Never messed with clamshell saws before so I'm not sure how far I'll go on it.  Need to stick comp guage on it & go from there.
Turned out to be 18" b&c but in good shape.
Should be able to part it out & get my money back I would think...

Run it you might like just the way it is.   Also here is your chance to learn all about clamshell crankcases.
Lots of options.

The 250 is the largest displacement of that series of Stihl Chainsaws.

At the purchase of the later Stihl 025 I have, I thought it was cute, and clean, and showed interest but after examining it, I saw that it was a clamshell saw.After pulling on the cord, I bought it.

Not having much hope for high Stihl performance from it, at home I started it up and made a couple cuts and was pleasantly delighted that it had a proper mixture in spite of the muffler mod and single needle carb and how well it cut. It had a yellow chain.

I read a little about them and reviewed IPL's and pulled the muffler on mine and saw that it was a four port one like a 250.

My 025 is a .325 X 16" one.

Some are 3/8LP.

Some are 18".

The bar is a different mount than the 026/260 and most have spur sprockets.

Except for putting a new twin needle carb on it, I have changed nothing on it since purchasing it from a fellow Chainsaw Repair member.

He ran it back in the winter in a comparison with a 40cc chainsaw and there was no comparison, the Stihl 025 run off and left the 40cc chainsaw in the dust.
We should share what we know... someone may learn...
That knowledge can live after us... and that "Pays It Forward".
Be all that you can be . . .

Well I'm not so certain it's just the plug .Fact about a week or two ago I dug through a box of parts and lo and behold the clutch cover from an 025 fit right on an 034 Super I'm going to rebuild .Thermo plastic but  it will work for the time being .
Now that's a deal .Once I was on the lookout for a clutch cover for an 038 mag .They wanted a tad bit for them on flea .bay .I got an 024 cover which is the same thing for half the money
