Hi all, 2002 Hustler SuperZ. Owner extremely dissatisfied with the Kawasaki FD731V engines these came with. Apparently, five of them were replaced under warranty. In any case, the latest engine, with pretty low hours, is leaking oil like a sieve. There is a small hole about an eighth of an inch in diameter in the case underneath the governor arm that oil flows from. It only does this when oil is within the normal range on the dipstick. If oil is at the add mark, it doesn't leak. Is there supposed to be a plug here or something? How do I fix this?
