Mcculluch parts needed.

I have a PM60 and a 7-10A and both saws need rebuilds and im having trouble finding parts. The 7-10A loses all power after it gets warm and its oiler dosn't work, whie i might be able to get away with just rings i would rather do both a cylinder and rings. My PM60 is the worst and needs the most parts (i shouldn't have bought it) it is really low on compression when its cold and my borescope shows the cylinder is all scratched so that means both it and the rings need done. The PM60 also needs the oiler fixed and a new fuel line, plus the previous owner cut a hole in the muffler and i would like to fix that. I will also need the gaskets for the cylinders for both saws, the oiler cover, and the PM60's carberautor.

I have already found the fuel lin for the PM60 and a piston and rings set for the saw as well.
Below are some pictures of the cylinder of the PM60 and the muffler cover . Please if you have any questions comments or leads leave a message or contact me.

Can't really see anything on that video. You'll need to tear it down. If the cylinder is toast you have a parts saw im afraid.

So what about all those little scratches on the cylinder walls do you think that would clean up with a new set of rings?

They probably aren't anything to worry about. They are not scores in the bore. Strip them down n have a poke and grope before you do anything. These cylinders are rocking horse poo

I suspect the scratches are from dirt and dust as when i got the saw it had no air filter and there is a lot of dirt in the carb box

Thats pretty normal for an old mac airbox.

Its straight up and down deep scoring thats the worry or chrome missing

Well thanks that puts me a lot more at ease with this project, as for my 7-10 losing compression after it gets warm do you think new rings will fix that ? The cylinder on that saw is really clean.
