scored chainsaw cylinder
I have a Husqvarna 272xp chainsaw. Last year I had to replace the cylinder, piston and rings. Now, again I have low compression, 65psi, and the cylinder is showing wear. If I put some light oil in the cylinder, I'll get 100 psi. I have never changed the type or mix of the oil over the past twelve years. I cannot find any crankcase leaks. Why do you think this is happening? And, do you think this cylinder can be cleaned up with a hone, or is it shot?
