Centrifugal clutch spring

[Kreepymidget]

Hey all i think this is the right section for this qiestion but if not feel free to move it to a more apropriate spot. Anyway im just wonderong if anyone knows the size of the single spring centrifugal clutch spring. Its the set that only has a single spring wrapped in a circle and conected to itself.
Oh and also if anyone knows where to buy replacement shoes for it as well.
