Answer to "Why is my food still chunky after blending?"My blender would not blend smoothly either. It use to make an unusually loud noise when I put the cup and start the motor. I realized the motor had a "play" making me believe it was not tightened enough. I took a look at the pics on this page and then realized it was assembled wrongly. The white rubber used to absorb the movement was placed after the motor was inserted. Thanks to all who have contributed to this Oster page.
