I wish this was the preservation of the original engine,� but the engine that I acquired with Hoover had a cracked cylinder.� . . I bought a replacement engine that "ran when I pulled it",� but the PO stored it outside under a tarp,� and it suffered water damage.
The engine would not turn over,� �this is what I found when I pulled off the head.
I was able to free up the engine,� but obviously with this much rust in the cylinders,� I needed to disassemble and check for the extent of the damage.
The pistons are removed, and the cylinders honed.� I am going to try to preserve this engine, without sending to machine shop.� It is very clean inside,� so was obviously rebuilt recently.� The crank and rod bearings are in very good condition.
