Echo CS-590 are my cylinder and piston too scored?

I just bought this saw for 100$ it starts good haven’t cut with it and haven’t run any compression test yet any thoughts.

I don't see any scoring......

I dont see anything on yours.

This one was scoring and still ran fine. Came to lean from factory.

It’s more on the cylinder it looks like maybe a new piston but it’s hard to get on photo from the exhaust side on camera it looks like one vertical score but there are a few but they maybe light

Watched the vid closer. I see what ya mean.

Use a straw or popsicle stick through the exhaust port see if you can "feel" that line left to right and vice-versa. If it stops yer pokey stick, may wanna pull the cylinder off for a better look.

imo I would replace it - and if you have transfer in your cylinder clean it up

Thanks for this saved me from tearing down the saw and luckily the straw didn’t catch at all so just a dirty cylinder it seems.

I would do a compression test. Certainly a LOT easier than removing the muffler or anything else to troubleshoot the condition of the P/C. I did a compression test recently on mine just to test the gauge because it was only showing 85 psi on a pretty new 372XP that I was working on. It went up to 155psi after a couple of pulls which told me the Husky X-Torque had some issues.......
