Took the engine apart. The gasket b/w the cylinder and the crankcase showed a little bit of leaking, not sure if that is a problem and whether that would compromise the compression. Attached are photos of the piston and rings. Put both rings in the bore to show wear, the top ring had a gap of 2 mm, bottom ring was about 1.8 mm. Other photo shows how loose one of the rings was on piston. [Linked Image]
