Think it should be set at 70* in other words, put the spring end in the hole with the #1 by it and the other spring end with the #6 by it and multiply (x) by 10 adn your clutch will be set to the 70* setting. If you find that your sled always seems to be in the wrong gear you may need to go to 80*. The twist of the spring holds the shift point longer so to speak letting your motor work in the proper manner(no bogging).
