So, Peter.....you're not a big fan of the Osmotor?.........8-) I remember Tom Cooper coming to a steamup in PA with his "Smokey Shay", and ticking off the host as he sprayed diesel fuel all over everything within 3 feet in every direction. It ran out of steam every 10 feet and had to sit there while it built up pressure again. Not a very impressive demonstration.
