What are these different settings for and what do they change? Mine is set at B right now. But the draw length is too long will setting the string in a different one change my draw length?

It has been awhile since I tinkered with a Mohave. However, I am guessing that the ABC settings are your string posts. Almost all of these style cams come with the string attached to the middle post...in this case a "B" setting. Moving the string position on both sides of the cam to either the A or C setting should move draw length approximately one half of one inch. Moving the string the post closer to the center of the cam shortens draw length while moving it to the outer post lengthens it.

Hope this helps.

Thanks i need to change my draw length. No one else told me i could to this. I will have to bring it to the shop and throw it in the vise and change the setting. Thanks a lot.
