Why is my MJ1200 with SureFlow mod doing this?

Ok, now you've got me confused. Always spins backwards? So it is currently drawing water through the front and pushing it out the sides/cage? I can't conceive of how that would work without the prop continually hitting the tab since the shaft & prop would be moving towards the front of the cage & tab? Where exactly is this tab located, at the front end of the cage, perimeter?? Should be a 50/50 chance that the thing will spin in either direction at start up and half the time not even hit the tab on start up. Just too difficult to visualize what you're describing.
