piston

My brother's MS291 lost power and wouldn't idle; upon inspection it seems to have a cracked piece out of the bottom exhaust side of the piston. See pics. https://photos.app.goo.gl/J3Pj9dtCPq3ExKqE6 Questions: 1. what would cause this piston failure? piston and cylinder seem smooth; crank...

I'm replacing the intake boot. Probably end up taking off the cylinder now also. So my question is on the second picture. There's a line on the piston and there's some metal on the edge of the intake ramp. Is this bad? Compared to tge new intake boot , the old ones mating surface gasket was...

Hello arborists! I've really learned a lot from this great forum -- thanks so much for helping folks out with their questions. I'm hoping to get a bit of advice on the piston shown below. It's in a used MS462C that I recently purchased for a good price -- it has great throttle response and...

Looking for a head and piston for ms291. Would like aftermarket if available.

Hey guys, I inherited this 372 X-torq with a broken piston. A chunk of the skirt on the exhaust side was broken off and there were metal shaving in the exhaust. The cylinder was badly scored. I went ahead and replaced the piston and cylinder with OEM parts. I broke in the new top end properly...

I have a stock 3120xp, maybe a year old. I was cutting some red oak yesterday and unfortunately the bar got pinched as I was making a relief cut in the log I was bucking. I was able to get the bar out of the cut but after that, the saw just dies when I try to go full throttle for cuts. Saw...

Hello I'm having trouble finding an after market piston for and echo cs341. I don't have the saw physical in hand but I bought it online and am trying to get parts ordered before it arrives. Does anyone have a clue what size piston It is or what saws share the same piston?

Hey y'all, I have two ms-261's that are both showing some scorch marks at the top of the piston on the exhaust side. They still seem to be running well and have good compression (by feel not with a gauge), and I can't see any scoring in the cylinder or on the piston. My question is, now that...

Pulled this piston out of my 262 I rebuilt a year or so ago. To my untrained eye it doesn't look too bad apart from some carbon on the exhaust side. I'd appreciate some feedback on the condition, so that I can learn more about what I should be looking for aside from the obvious like scoring...

Hello, I'm pretty new on here, used to be a lurker until recently. So I just got a new MS 261 (ver 3/carb) this spring and scrolling around during that time (including that 400-500 pages oil thread, oh god) I noticed that the veterans on this site aren't big fans of this oil. "Smells bad"...

This is the second time this has happened to me on this saw. The first time my dad put straight gas in it. It looks similar and I used acid and sandpaper to clean the inside of the cylinder and just added a new piston. It wasn't perfect but it looked pretty good. I am wondering if this...

I'm just bored with saws, and really don't have time to fool with them anymore, trying to keep my wife healthy. They are all for sale individually, for $55 shipped each. They are all "open box", some I've had for awhile, some are pretty recent. They are as-is, as I'm just cleaning off the bench...

I have an MS650 magnum with a scorched piston (and possibly the cylinder) that I’m working towards repairing. Looking for OEM parts to make it right.

Is this muffler OEM? And is this carbon buildup on the piston head normal? What is this piece? The one circled is the unknown piece. I have one that goes to the oiler gear but idk where this one came from Thanks!
