Ladies and Gentlemen,
Lets be clear, if on a TCM or LYC piston engine you hear a wizz sound but propeller does not move. Your starter motor is working fine. You have another issue!!!!!!!!!!!!!!!!!!!
That needs to be confirmed before you think it is a great idea to hand start.
It seems the folk that have done here seem lucky, not well informed or WELL INSTRUCTED at all.
But I hope you are never in that position - I have been, I wait for the rescue team and rink beer on the Monday if need be.
