Guy who sold it thought the bearings were shot... oh no... just a little gummy. Inside is perfect, bearings, gears, piston/sleeve: all in beautiful shape. This is my first saito... nice engine. Just wish i hadn't bungled the case.

I did take a scouring pad to it and it scrubbed off the black ... but there's no way i'm gonna get it all... i'm wondering if Tarn-X will take off the oxidation? Anybody try a mini sandblaster?
