I've hand propped and started my "532" on many occasions when the old battery was just not holding a charge. I've hand propped 150hp Lycomings but I'm a bit leary of hand propping my 80hp Rotax if the need should ever arise. Don't know if its age and wisdom or I've become a "Wuss" in my old age. Has anyone hand propped a 4 stroke Rotax and been able to tie their own shoes afterwards?
