I need help with motor timing.

Like a fool I moved the endplate on my new promax cobalt 4014 before I marked it. Now I have a few questions. Everyone talks about reversing the polarity and adjusting the timing, but I installed a apc prop backwards (tractor for a zagi) and I don't need to reverse the polarity. I don't understand why everyone talks about reversing the polarity and adjusting the timing. Did I do something wrong?? Why does everyone talk about it? I set my timing to be about 20 amps static with an apc 6.3x4. Is this way above the efficiency curve? The stats say max 20 amps, but I assume the amps will drop to about 18 amps at speed. Does anyone have suggestions for what kind of current I should see with this prop. Should I go for a 7x4 or maybe a smaller prop. I don't have a lot of experience in propping electric motors. I need any advice anyone has. Thanks for your help again everyone.
