Has not been flown or started since 2008, according to log books...widow will not allow engine to be turned or started until new owner takes possession.
That's a rather unusual stipulation. With an engine that hasn't been started in 8-9 years, and not allowed to turn it, a cautious buyer can only allow not much more than core value for the engine.
I think the stipulation is due to the situation - I suspect an estate attorney has advised her to sell the plane "as is - where is" to minimize liability.
When my father passed our attorney said not to drive any of his cars. If there was an accident the estate could be sued.
If someone "inspected" the engine (started, turned prop, etc.), and someone else bought it and the engine failed, they could sue saying that if it hadn't been "improperly inspected" it would've been fine. They might argue that turning the prop without running just wiped the oil off the cylinders, or that a ground-run without flying doesn't warm up the engine enough to remove the acids and water-vapor by-products of combustion
Also, right now the engine's condition is big unknown. Turning the prop, or starting it, would answer that question. And it likely won't be a good answer. By leaving it alone, the smart money will bid accordingly, but there'll be some people bidding higher, willing to take a chance.
I hate to say it, but "hands off" is probably the best option for this widow - the most return for the least effort and expense.
