I'd be on the fence about that one. Especially since new meteors are $40.
Would you keep this piston?

I would al least try cleaning it up with some industrial Scotchbrite and WD40.

Sure is embedded. I just wiped it down with some WD40 and they are still there.
I'll give it a fine sanding tomorrow and see how it turns out.
I think these cylinders I have are from that time frame, does not bother me much as I port each one before using them but if they were put in by someone that don`t port then they would do some damage to the pistons.
That might change my opinion on using it again if that stuff really is enbedded, really hard for me to see that from just a pict.

I'd be putting in a new Meteor. By the time rings got shipped here (Canukistan), may just as well have a piston in the box too and keep the old one as a spare or vise versa.

That piston is dust
Don't sell that to an enemy

I'd use that piston in a heartbeat.
I would buy pistons that are worse than that.
Clean the saw REALLY well especially all carbon from the cylinder.
Buy a new set of rings and don't look back.

The piston is toast. I've replaced better. Think of it as an investment.

What was compression before pulling it?
I have one that is 100% worse! Pulling 152lbs.
Ya, the chance is there, but it is a tool.
Be on the safe side, buy a new saw. LOL!

Well I guess if I was building a top fuel engine for John Force, I might not use it.
In a chainsaw that I use weekly I absolutely would.
In a saw that I'm only gonna use occasionally..................are you kidding?
I guess I need to get on the salvage lists of some around here

So…..if the piston measures with in specs…… ie….not too loose in the cylinder…it’s the rings that do the sealing against the cylinder. Granted, the rings need a good groove to seal in the piston. That piston with good ring(s) should be just fine. Am I missing anything here?
I agree….a new saw would be the REALLY safe move! LoL!

Need a photo of the piston from the bottom to compare skirt wear.
Using the photos provided I would clean it up and use it as long as the very botton of the skirts is not to thin.
Index the skirts and crown with a razor blade to check for high spots and figure out why it got so hot.

C'mon guys, quibbling over a $40 piston & rings in a $600 saw ?? even if it is only used occasionally why would you "cheap-out" when the saw is torn down already ??

What does the cylinder look like? Is there carbon buildup around the exhaust?

I'd clean it up and run it. Install new rings of course. Was the mixture a bit heavy on the oil side or running a bit ritch?

Add me to the list of folks saying find out why the piston got scratched up, regardless if you clean it up & re-ring it, or go with a new piston.
