you can go to the top of this thread and there is a sticky about cam timing, it is on the hoyts cam 1/2 but is still a 2 cam system and will be the same directions with twisting the cables to get the cams to rotate and stop at the same time. You can also buy a book from Larry Wise called tuning your compound bow, get the third edition, lancaster and cabelas both sell it, the book has pics and covers dual cams and solo cam timing as well as making serving repairs.

You could also log onto www.martinarchery.com and there is an explaination on how to time the Nitrous cam. Although it's not the same cam the process is still the same for any dual cam system.

Wise's book is a good read, but you don't really need it to synchronize your cams. (BTW there's a difference between timing and synchronization, although many archers [and a lot of magazine writers!] confuse the two terms.)

Just draw the bow back and feel as it hits the back wall. If you feel a solid "bump," then it's synchronized. If it feels "bump-bump," then one cam is bottoming out before the other. If so, twist the buss that attaches to the cam that bottoms out first. Repeat until you feel them both bottoming at the same time.

Sounds hard at first, but it's really easy as pie once you do it a few times.

I'm guessing here that this is a hatchet cam, right? And the lobe of the cam is whacking the string when you shoot, right? This is an indication of an elongated string (creep) or a string that is just too long in the first place.

They should be rotated so that the flat part of the lobe is approximately parallel to the string. This is done by shortening the string by twisting it or replacing it, depending on how much has to be done. Actually it doesn't hurt to go just a little bit farther on the short side to allow for some more creep. Maybe 1/8" or so.

Now I'm going to pick on you some. If you shot your bow enough you would have noticed this a long time ago because you would know that for this to happen the draw length would have gotten longer by at least 1", which you can tell if you're familiar with your equipment.

could you please post a pic for us to see what is really going on, sounds like your string has streched.
