I have an engine that has been sitting a couple of years. No logs. I want to sell it. Am I better off breaking it down and certifying the major parts, parting it out or selling as is complete?
 
Depends on what it is. With a certified crank and crankcase, it has a lot more value than as a "no logs, been sitting" engine, IMO.
 
I agree. Some details, please?

I took it off a cub I rebuilt a number of years ago and it has been sitting in the back of the hangar forgotten about. It is an 0-235. It was unbolted and put in the corner.. logs are gone fortunately..
