Yes found the problem. When i rebuilt the engine i checked the sizes of everything thinking i could you some parts again. Big mistake. It was the little ends in the conrods and the gudeon pins. They was a tiny amount of play. I got them checked and renewed. Icould see when the conrod and piston were put in a vice i could see the amount of play. The piston was slapping about not through bore wear cuz it had a rebore but because the amount of wear of the little ends.
