So, I've tried moving the motor forward, and managed to move it a little bit... But not enough. It's sticking out about 1/32 of an inch... So close. I'll try for a bit longer to see if I can get it to move any more forward.
Edit:
I'll add that what I had to do was to tighten the curve of the motor mounting bracket by holding it with a vice and flattening the curve with a hammer. It tightened just enough to move the motor in some.
