I have a nice Stihl 290 Farm Boss that I received with a scored piston and cylinder. I just installed a 49mm (390) aftermarket piston and cylinder with decomp. While I had the saw apart I went ahead and opened the muffler up a bit and port matched the intake and exhaust. The saw starts, revs, oils and idles as it should. You can see where I cut a small hole in the top cover for the decompression port (there is a little scratch where my exacto knife slipped)
Other than a couple scratches here and there the saw is in great shape.
