I had this happen twice so far and I have only owned the plane for two months. When I crank the engine it seems to suddenly have a kick back and the starter disengages. I let it sit for a minute and the she starts and runs fine. It did it when I tried to start her when it was 27 degrees out when I bought her in Idaho and the. She did it tonight and its almost 55 degrees in Socal. What causes this and is it harmful or fairly common?
