Engines are like women they are contrary things and you don't always know what they are going to do next. Having been struck by a prop once I decided never to go there again. The major difficulty for me is being left handed and the whole process just doesn't work for me. I paid $30 for a starter and $60 for a battery so I use them each and every time I start an engine, thats all sizes no matter what. Getting hit by a prop is painfull, as we get older wounds take longer to heal and quite frankly my blood is far to valuable to lose because of my own stupidity.

Us an electric starter each and every time.
