After deciding I wanted to rebuild this MS250, I started pulling it apart to see exactly what I needed in addition to the crank. I really don't see any scoring that I can feel with my nail on the piston or the cylinder. I couldn't get a good picture of the cylinder, and at the top I can see a few marks where you can tell the rings have just been sliding back and forth, but it isn't any scoring that I can feel with my nail or anything and it's smooth to the touch. However, there is a bit of discoloration and a fair amount of carbon buildup on the top of the piston. Since this is my first rebuild and you all are a lot more knowledgeable than I am, am I good to go reusing this? Or would you recommend replacing it while I have it apart?
