When you do that there is clearance for the nut when pulling the gearcase.
Not sure I understand this part completely. So the nut (in my pictures above) stays on the end of the 1/4 inch copper tube that it’s attached to, correct? So what exactly did you do with the altered spade bit?
Which slotted nut did you use the spade bit on? Maybe this will be clear to me if It remive the powerhead? Do I need to remove the power head for sure?
