good chance.

I would like to see the piston too It might have been straight gassed.

look at the 4th pic in the 4th post.

OP, can you post a pic of the intake side and exhaust side of the piston so we can figure out what possibly did this?

Exhaust side pic is up there, intake side incoming.

That got way too hot, connecting rod tells the tale add a new crank to the list.

Yeah if I’m gonna rebuild this saw, might as well replace the crankshaft. At this point I’m leaning more towards used oem parts.

That’s what I hope for when I bought this saw. But it’s strange that it’s been obviously in use for a while even the gas residue appears to be mixed. It’s unlikely the same person using it before put straight gas in it.

Definitely OEM you can even find some used parts for that saw on here.

Pics of the front and back of the piston will help.

I get a lot of 2 stroke equipment that was straight gassed but the customer will pour it out and put premix in and then lie about it, sometimes they try and fix things and do damage also and same thing they don't tell me what they did and I have to try and fix what they did and it takes me longer to diagnose when they do things like that.

Prob a lean seize.

I watched a video on YouTube. One guy shows how to rebuild a ms460 top end. He recommends to use only one ring on the piston, any thoughts?

Bad carb adjustment? Fuel clogged up?

Air leak, somewhere from crank seals, gaskets, intake boot ripped. Check the carb adjustment screws very carefully, count how many turns out they are at now they should be around 1 out on each one.

Don't rely too much on everything on YouTube.

 

[stihltech]

Do you want to put good parts on top and have the crank come apart? Very good chance with a blued rod.

But if it is on the internet it must be true!
Wait, hang on. I think I won a million dollars. The just want all my info first.

Intake boot looks good, gasket is falling apart when I take cylinder off. Don’t know where the crank seals are, I’ll have to look for them.

Under the flywheel and the clutch.

one more thing, the plastic brake cover melted, maybe someone ran it hard when chain brake was on?
