RE: How does big two stroke engine sounds like ?
I'm anxious to run the rebuilt 4500 as a Diesel, it will turn a MasterAirscrew Classic 20x10 at 7,000. It may sound pretty nice like that. I was waiting for a new piston for it but gave up and used the old one that had chewed up its original circlips, the top is pretty beat up. I cleaned out the ring groove, installed the new ring and it seals very well.
