I know that it is not the newest post, but I have the same issue.
I have new EQ3-2 and I was hell of a wondering why I see nothing on my second session (firs time I was looking for Tycho nebula, which is visible only in X-rays). I ve put water-based inclinometer on it and realized that the one pointer with black triangle is correct, the other white one is exactly 10° off. Actually the correct one is quite hidden with Dec motor and if you are watching starting with west Dec move, you better off using the bad one pointer and just subtract 10°.
I see no reason why it is off and my guess is that it is construction mistake?
