Clutch throw: the distance the mandrel moves to disengage the pressure plate. It doesn't have to move much, just a few millimeters. Look at the clutch cam in the side case. It only pushes the bucking bar a little way when the cable pulls the lever inward. Adjust the flower nut to where the pressure plate doesn't drag on the friction pads (disengaged). There should be a little slack in the clutch cable too. Check the play at the clutch lever and the hand grip. There should be about 3mm of play so that the clutch cam isn't riding on the bucking bar when the clutch is engaged. Look at the gap at the hand grip and adjust using the cable adjuster.
