This summer, my generator quit charging. My [EMAIL PROTECTED] couldn't get to it right away, and I did not to be grounded. With no previous experience except for watching an older gentlemen hand prop a Cub many years ago (he stood behind the prop, held onto the strut, and swung it through), I managed to hand-prop my C75 all day. I swung it from the front, using the tecnique that I had seen many times on TV watching the old aviation shows. It is almost identical to what Bob described. VERY easy to do. Instead of chalks, though, I tied the plane rear tail hook down to a ground anchor in addition to the brakes. Also, always prop with the throttle at idle. The only real deviation that I use is after priming, I pull the prop through with the mags off to ensure that the cylinders all have a fuel charge in them. This was verified by my [EMAIL PROTECTED] who has worked on planes for 40 years, and told me that doing that would ensure that the engine would fire off on the first try. He is right. First flip every time, although that only adds up to 8 hand-props. Dennis Schmaltz 94715
