Question 1
This engine (OS .46 AX) was never fully broken-in and sat for close to four years with after run oil in it. It still has good compression, but oil is leaking out between the drive washer and crankcase. Can I just continue with break-in where I left off and is it possible an internal washer is bad?

Question 2
I was in a rush to start flying four or five years ago (never did) and assembled the wing uneven as seen in the picture. The fin also looks like it is slightly warped to the left in the second picture. Should I assemble a new wing and replace the fin?
