It is a bit off. The air hole lines up with the drain hole so positioning the coil to it would not be ideal. I have some extra rings in the package so I will experiment with them and see if I can get it to "unclock" maybe 15-20 degress.
Yeah, when after adjusting mine, if I take the atty off, since the 510 is reverse
threaded it will back off until it it gets to the end of it's
thread travel. It does not remain in position. Not really a problem, as Mr O'Neil noted there is no reason to be taking the atty on and off. So just need to readjust when that time come to remove and clean. Others note that it remains in position though, hence my head scratching.
Ahhh, had not done that, will get to it next bottle change.
EDIT: Attempted o-rings to adjust the position of the air hole to center on coil, or at least mid way between the posts. Neither one one was acceptable. Other options? Sanding? That would mean it has to go almost a full revolution to get to the place I want it correct or does sanding back it off counter clock? Drilling? Crazy that this should be necessary

Air hole is located at about 11 o'clock in photo, just in front of that wick/over the drain hole.
