I'm building a log splitter and found a Vanguard V-Twin motor on Craigslist for 300 bucks. It's off a roof cutter, guys says it purrs like a kitten and he can start it to let me listen. He doesn't know how many hours, nor does he seem to know much about the history of the motor other than he bought it for his tractor but then found a Kohler instead. Can anybody give me some info or advice on the Vanguard? Good motor or not? Anything to look for? Thanks!
