Yes needs to be turned so the slot is lined up with the wicks
The first thing that you need to do is find out how the slotted part of the post is attached to the deck itself. One would assume that its slipped over a stud, which is then itself mounted on the deck, so that the slotted piece is mounted over it.
This would be the ideal.
Look at the bottom of the deck (pics would be great). Lots of time you can see where and how the posts are mounted on the deck. This will let you know what and how you can move the posts.
Anyways, as long as the slotted part of the post isnt permanently soldered to the deck, you should be able to move it. You will need:
1) Needlnose pliers
2) 2 Rags
Put a rag or napkin over the post so that the pliers wont scratch the atty. Use the other rag to give you a good grip on the bottom o the atty.
Twist the post into position.
Unless the slotted portion is soldered to the deck, this will fix it. It is going to be a constant issue, though.
Hopefully you can tighten it down somehow.
As I said, pics would help troubleshooting this issue.
Let me know how it goes
