Ah ha! Or is that "doe!"
I have no idea how I missed the print that says "back out the gauge three-and-a-half turns". I guess I just set the tool, then pulled it and measured it, then freaked out before reading anything more.
All's well, thanks again for the guidance.
This is almost done, just need the valve body from Lentech (the price just keeps going up on that, it's like they don't know we're in a depression
).
