Carter/Eddie AFB question

I have some 1405s as well . I was thinking about that . I will try one of them . Really don’t want to drill the bleeds on the 1406 while just messing around .
But the 750 competition shouldn’t be calibrated lean .
Is it a 1407 Eddy? They had tons of issues. I have one I couldn't get right no matter what I did. Google it. lol
