I almost forgot what I wanted to say here (please stop me if I ramling). I took my engine appart tonight and the connecting rod looks much better than I remembered. It is not bushed but it looks strong and has a lubrication hole (see pict below).

I cannot find anything wrong with the bearing surfaces of neither crank or case. Both parts look shiny and well mated, it is possible that the mating prosses is what I have felt and misstaken for a large wear, but still I cannot believe that it is meant to be this sloppy. I can clearly wiggle the crank in the radial direction. [:'(]

Fitting the crank in a new case gives exaclty the same sloppiness, I find it hard to believe that it would be the crank that has been worn rather the bronz bearing though. Guess I will just have to run it some more and see what happens...
