I have a saito 65 that has given years of good service but over a couple tanks of fuel it started to run erratically. It felt stiff when I flipped it over so I took it apart to see whats up and found that it was dry as could be inside. If I oil it up good it starts first flip and runs great until normal blowby pushes the oil out of the vent. Anybody got any ideas. Its a great little motor but I'm stumped on this one as I don't see how its possible. Fuel prop tank or plane has not changed.

I had a Saito .80 that did the same thing & I replaced the piston ring & cross hatched the cylinder wall with some 400 sandpaper . The old ring was stuck & the piston land was full of carbon . Worked great with the new ring . Good luck , Max H.
