Snowmobile engine centrifugal clutch assembly? - snowmobile engine centrifugal clutches

I have a Yamaha 1972, and on Snojet reconstruction of SST in the end. But at the end of my clutch for spring and weight assembly. Now I wonder how we should keep it. The pieces they have left is a shining example that the screws in the shaft of a small ring and the open end of a washing machine with a hook on one side. There is also a wood about an inch of the tree, and I do not know where to find them. Suggestions would be helpful. Thanks
