So the journey continues on the 288 I picked up earlier this month. Compression reading is 150 with my Echo compression tester. Not real low, but not great either.
I had the muffler off tonight and when looking in the exhaust port the piston definitely had some light vertical scoring (can see it, but can't feel it with my finger), and the same light scoring can be seen on the cylinder.
At what PSI reading do you guys typically dive into a saw and rebuild it? My understanding is that a healthy 288 should be between 160 and 180.
