As l wrote before, there is quite a bit of play when I hold the piston stationary and rotate the prop by hand.
The big end of the con rod looks ok, I can't see the small end that's on on the wrist pin but I suspect that's where the play is.
Im going to send it to be checked out soon.
Ed. Thank you all for your help!
