I have yet to "suffer" from CAD
Here's a saw I had planned on putting together but I just have too much stuff. This was a homeowner saw that ate something through the intake. I cleaned the cylinder and it looks pretty good. No grooves. I gave it a light sandpaper hone afterwards. The only damage I can see to the saw is the top cover does have a crack on the top. Please look at the pics. There are no seals in it and the bearings feel pretty decent. I had planned on snagging in new piston and putting it together but it's your option now. I have all the little bits and pieces so I don't think you'll need anything but a piston, rubber, and a gasket set. $200 obo pho plus the ride.
