I was messing around earlier today with different draw weights on my new Liberty and it seemed fairly easy to back the limb bolts out. I made 5 full turns. When I went to put the limbs back in their original position (bottomed out at 72lbs), It was extremely hard to crank it back down. I was only able to get 4 full turns. Go figure [:@]. However there is no gap between the limbs and the riser and it actually feels a little stiffer to draw back. 3 questions:

1. Can you overtighten the limb bolts?
2. What could have caused this problem?
3. Would this cause any sync problems?

Thanks for any info ya'll can provide.
