Step # 1
Before you start twisting the string and cable for cam
rotation. Move the nock or loop up and down the string to see if it helps you get a bullet in paper. If it has no affect then
follow steps below.

Before we start the twisting of the cable or string for
cam rotation its important to try a nocking loop that is set up like the picture on the side. This may fix the problem without
having to play with the string or cable. Adjust your loop so its under the arrow not in the middle this may fix the problem
and give bullets.

If you don't use a nocking loop then you can use two brass
nocks or tie in nock under arrow like the picture on the side. Make sure to have a small space so nock is not pinched at full
draw. Pull under the brass nocks or tie in nocks.
Step # 2
If the nocking loop or nock set up doesn't work then the
next step is adjusting limb bolts. If you are getting a nock high in paper then take off 1/2 turn on the top limb bolt and
level the nocking point. It should have moved so level it up. If you are getting a nock low then take a 1/2 turn off
the bottom limb bolt and reset nocking point so its level. The combo of step 1 and 2 can sometimes give bullets and good arrow
flight.
You may need only 1/4 or full turn on limb bolts. If you get a bullet with
these adjustments your good to go. If you don't see any changes then its time for twisting string or cable for cam rotation.
Don't go more than a full turn on limb bolt if you don't see any changes in paper tear.
Step #3 Cam Rotation
| Mathews Cams have timing holes for cam rotation. |
|
|
Now that you have tried step #1 and 2 without any luck
reset limb bolts so its back to the start or at factory setting. Solo cams are normally just bottomed out and Hybrids are
set even tiller. Some solo cams and Hybrid cams have timing marks on cams to show the proper rotation. These marks are
not always right. The best way to find the right rotation is paper testing. The picture on the side shows the timing holes
on a Mathews cam. Solo cam bows that use mods can cause alot of problems and change nock travel bad. Paper testing is the
best way to find proper cam rotation.

| Under rotated cam! |
Set your bow up so the rest and arrow is level.
Paper test bow. If you get a nock high tear the cam is under rotated so add 6 twists to the cable and level nocking point.
Test again. If your tear is getting smaller continue adding twists and leveling arrow until you get bullets.

| Over Rotated Cam! |
If you are getting a nock low tear in paper then your
cam is over rotated. You fix this by adding 6 twists to the string. Reset nocking point so its level and test again. If the
tear is smaller then continue to add twists and level arrow until you are getting bullets.
If rotating the cam gives you bullets then your good to
go. Some cam designs you can't fix by rotating cam because the problem is in the cam design and rotating the the cam won't
work. The cam doesn't let out the right amount of string on the string tracks or the mods for draw lenghts affects the amount
of string that is let out. Step #4 is the last thing you can do to fix the problem.
Step #4

|
|
If step #1, 2 or 3 doesn't work then your at the last
resort. The last thing you can do to fix your bow is to change the size of your idler wheel. If you are getting a nock high
tear in paper change from a 4 inch idler wheel to a 3 inch idler wheel. You will have to change the string lenght to match
new wheel. This changes the string angle to get bullets. If you have a nock low tear then change from a 3 inch wheel to a
4 inch wheel. You will have to change string lenght to match larger 4 inch wheel. These should be a last resort. If this
doesn't work contact me. Thanks Mike
