RE: OK newbs, Learn a quick stupid bit of advice from me.
I had almost the same thing happen to me about 5 years ago.
I went to flip the prop to start it and the engine fired backwards (didn't start).
It didn't cut my fingers but put a huge gash down the palm of my hand. (That was the last time I attempted to start an engine without a chicken stick or electric starter)
Link Minnflyer, I think that scar will be with me for life!
I didn''t get stitches, but went to the ER to have it glued back together.
I didn''t continue to mess with the engine at the time. I am a wimp went it comes to blood, and there was a lot!
