Said news, my engine failed....
My last flight was week ago and there was no issue at all, I didn't hear any strange noise whatsoever. After flight I took my plane home and it was staying there untill yesterday when I went to the airfield again. After refuelling I wanted to prime engine but prop stucked after turning 180deg. Then I tried to turn clockwise but again it stucked after half turn. I removed spark plugs and looked at piston heads for any signs of loose metal particles but it looked ok. So I went home, put plane up side down but still something was blocking engine. When I put my plane vertically on to the nose and to the tail I tried again to turn propeller and....it turned freely all way around. I decided to open top cylinder to look at the crankcase and bingo: bottom part of piston head found broken with remainings in the crankcase.
This is so disappointing. Such a failure after just few flights.
Any ideas what might cause such a failure?
