      It doesn’t take a lot of twist in the crank assy for it to rub the cases.

      The shaft has to seat on the bearings. You might need some bearing shims. Crank should have at least .025″ wall clearance.

      Crank shaft may have become lose, or someone lost kart at a corner and spun backwards, and while going backwards kept pushing the throttle, instead of waiting till fully stopped.

      Or someone simply just accidentally dropped the engine, and landed on the shaft bending it, knocked it out of trueness or round.
