I was just taking a look at it. I'm thing I know the problem. If you look at the picture I have you see the three (i'll call them pads) pads with springs on them. I'm guessing these need to expand and grip the side of the cover they are in. But they are not gripping, and this is the problem? The belt is looped around the out side cover. So when I kick start it pulls the belt and also spins the outside cover. But the three pads on the inside are getting no contact with the out side cover. I've never worked on anything like this, do these need to be replaced?
