I have a question, something I've been wondering about for a while..
At my gliding club, our Motor Falke is usually last to go in the hangar. And so first to come out. Routinely, whoever is moving it will pull it forward by the prop. I've done this a couple of times myself, but since reading this thread, I've not touched it. I did ask someone about it, and was told "no, no - prop couldn't possibly turn by itself". There was some mechanical reason given as to why this couldn't happen, possibly magneto-related, but it was a while ago and I can't remember the exact basis.
Could someone please tell me I am not nuts to be leery of this? I just have a nagging feeling that if I'm right, it's something I should be mentioning to our CFI..
