Help with Comet 20 driver

[vd2021]

Good day all. I am new here and found your forum while searching for help with a comet 20. I purchased a well used go kart that has a b&s 5.5hp engine and a comet 20 torque Converter. There was no belt when I purchased it. I took measurements and ordered the belt. The belt arrived today and I installed it. However the belt just sits there and the movable part of the driver does not come out to engage and move the belt. I found a pdf for the system, dissembled and used a wire brush on my drill to clean all of the parts to a like new condition. it then moves a little but only enough to just move the wheels (I have the kart on hack stands). It seems to me that the springs are not allowing the zinc shoes to move. I tryed it with one spring and it still does not work. Is there something I can do? Help. Please.

Thanks
