Things I learned while installing my witch.
Steve mentions in the installation video to make sure the witch is not rubbing on anything. I checked mine and it was rubbing on the two silver metal brackets in front of the witch when it raised and lowered.
The bracket that the witch is screwed onto was slightly bent from the factory. Make sure yours is perfectly flat. Second, at the bottom of the bracket, there are two screws that hold the bracket to the black colored base. The metal bracket has two slots, not holes, that the screws thread through to hold the bracket to the base. I had to slide the bracket rearwards to keep my witch from rubbing. So the bracket is adjustable forward and backward.
Edit: also make sure the witch bracket stands up straight. If not, your witch might lean slightly forward or rearwards. It also might end up rubbing on something.
Lastly, once I had the witch bracket straight and adjusted rearward, the top of the witch bracket that her hat would normally screw into, would slightly rub against the flames and well wall. So I ended up bending the hat part of the bracket closer to the witches back to stop it from rubbing.
I would check that the bracket is straight when you have the witch removed. Since you will no longer need the hat tab, I would bend it ever so slightly towards the witches back. And lastly when installing slide the bracket rearwards so it hopefully does not rub.
