Here's the MS271 I bought off eBay. PO straight gassed it. Doesn't even look like it was used to cut anything. Cylinder was salvageable and I scored a new OEM piston off eBay as well (bought before I disassembled the saw). Rebuild was going well until I noticed the piston looked different than the one that came out. Got on the board here who helped me to realize that I actually had a newer version and that they had changed the internals. So it sits here waiting for the new, correct piston to show up at the dealer; 2.5 week back order.
So I went ahead and replaced the cylinder and piston on a MS250 that I had previously got running but only had 110 psi compression. 170 psi now...
