Look harder (IF you really want to find out). I DON"T have any axe to grind. I was flying 2 strokes then and it was common Knowledge. The 582 quickly became the PREFERRED ENGINE in the 65 Hp range. I'm careful with all things and have never had a 2 stroke fail. There can always be a first time but the More careful I am, the More Lucky I seem to be. Nev
