Strange find inside a ms390!!!!!

[Khntr85]

Did you scribe that mark around the piece of metal on top of the piston? It looks like to me someone tried to epoxy that piece on there, to raise compression. Perhaps that mark is where they lined it up.

No, I just happen to see that outline on the top of the piston, and when I put that slug on there it matched up perfectly....

I didn’t get a chance to look at it last night, we take the little one to swim on friday nights after work, so once agian I got no “saw time”, lol....

Sounds like a brigs mower lol. and thats more like a 391 or something with that fancy spring av action.

Don't 390's have orange tank handles? Usually white handles mean pro Saw. I'm not up to date on the newer versions though...

Yes the the 390 have orange handles. But Stihl made the 391 with white handles in the hopes of tricking people to believing its a pro saw lol

my local stihl dealer has a 391's for $599 next to 362's for $749. They look very similar and the description tags do not explain much so anyone who doesn't know the difference usually leans toward the 391

Same deal here, and I've even heard the dealer "upsale" the 391 to people, because in his words, "Stihl messed up the pricing, you're getting more saw for less".

Keep in mind, this is the same dealer who threatened to have my house raided by the feds for having bought and built a huztl kit. Also the same dealer who has told me multiple times that "normal folks" shouldn't buy pro saws because, ya know, they aren't pros... Sigh.

That douche needs a swift kick in the sack. For multiple reasons.

Technically he is "right" you do get almost a pound and a half more saw.

Why do people even talk to *a-holes like this?
Do business with them, never!

Homeowners are orange or white or solid black. Every pro Stihl is white with the black insert on top.

I'd stop going to that guy. He probably rips people off for servicing saws too.

Sorry guys, did I mention I have been busy lately, lol...we have 5, yea I said 5-Christmas trees up threw out the house, and just got done decorating the “main” tree....the social director absolutely loves Christmas and she basically starts in the 1st of November....the channel basically stays on the hallmark show channel to....

The way I see it, she puts up with my strange hobbies/ways and what not all year, so I have learned to give her 2-months of Christmas stuff, LOL

Anyway back to the saw....I realized that this is ams290, not a 390.....as I said, it has been a few months since I tore this saw down....

Anyway her are some more pics......





If you look close you can see the imprint at the top of the inside of the cylinder...

I don't think that's the case anymore? Seen some like 271 or 280/81 that have white/black handles !! I don't consider pro saws??

Perhaps it was someone's idea of a 'piston stop'. Just slip it in the exhaust port to help get the clutch off, then he forgot about it or couldn't get it out. I'm surprised the engine didn't grenade. I would never have thought the engine would have run for more than a second with that in the cylinder.

 

[Stihlsmoking]

Almost all the farm and ranch have "pro looking handles" ??

And iirc the 271 and 291 share the same chassis and the 311 and 391 share.

It doesn't appear to have" bounced "around in cylinder much ?
Just one mark one piston and cylinder.
