Yep, Dick, Burt was that what Lockhart and Arfons was on four wheels, just to call some names and Warby on water....
racers without a engineering background....they simple know it.....for Burt, very often it was....try it, test it, fail....try again...get it running....
in Germany we had a so guy, too....Herz....the engine he used in 1956 was his masterpiece....the NSU engineers got this engine never running....he worked it out...he was a carpenter....
