I remember Harry and his Ucon oil based fuel. When visiting World, he and Craig Asher were out back, testing and running the screaming Super Tigre's, getting all they could out of these engine's. When Larry Leonard was winning pylon with the K&B 40's, I believe that Harry and Craig were on top of the curve with Garofoli, developing the ABC cylinder assembly. They got these engine's into the right hands, K&B never caught up.
Listening to Harry talk about his flying days, was a real treat. Harry would use both hands, showing how to come in behind another plane, position to shoot them out of the air. Great person, true American hero.
