Tri Power Power Valve

Read many items about modifying the power valve spring. Cutting coils, but everyone seems to have a different amount. Others say by weight 150grams, 1 60 grams. It probably is trial by error. As a starting point anyone know the weight of an original assembly for a 66 center carb?
