MM,
thanks for posting the photo's.
You do have the correct pilot, but it's attached incorrectly.
There should be a slot in the front motor mount that the tab/tang on the pilot should slip into.
That screw may be the cause of the problem, by creating a short on the center rail.
If there isn't a slot in the front motor mount, you can try tweaking the pilot frame 15 - 20 degrees below the horizontal plane, in front of the screw to raise it up off the center rail.
