stecz20: I am at the fire house. 7pm-7am. OSO helps pass the time! The engines were built by Carolina. This is who Tres recommended and this board gave me a favorable reply towards them as well. I did have a few negative comments when I asked the board about them, but the favorable comments outweighed the bad ones 10 to 1. They sound great on the hose, but we'll see how they actually run in another week or two. I'll keep you posted.
