That powerhead looks like it sat in rodent piss as well….Too much money for that risk…
I am assuming you have bought this engine, correct? If so, go ahead and pull the cylinder head off to have a look, so you know what you are dealing with. The powerhead sure looks shot, but you never know….Never judge a book by its cover, I keep learning this the hard way….
Have you drained the gear lube? If so, how does it look? There is much more wrong with this engine than just the suspected bad powerhead, you need to pull it apart somewhat so you know what you have got, then make the decision about rejuvinating this thing…
