Sounds to me as though you're on your way to a long and successful archery career. That's the best way to learn how a bow works. Tear it down and put it back together. One thing though. Always take pictures of string/cable tracking, cam position and such.
There aren't any cam timing marks on Martin cams. Set the bow up the way you want, get the brace height and A2A close to specs by twisting cable/string. Set the draw length and draw weight and get to shooting. Maybe a hundred shots or so just to settle the string and get rid of initial creep.
Then measure everything again. Take pictures of the cam from the side and post them. Also measure how much string groove is showing where the string comes of the cam. I think there should be about 1/2". Maybe 3/4".
How's the idler wheel lean? Did you get that part right?
