Carb issues with secondaries

[IndifferentJester]

Hey guys, recently replaced/cleaned bits and pieces in my carburetor due to sticking and leaking issues (which is now fixed). The only issue I haven't been able to solve is my secondaries not engaging due to my secondary-lockout-lever being engage. The only way it becomes free is if I jerk/slam to WOT. If I try gradual/slow throttle to WOT it still locked.

To better illustrate I give you my amazing paint workmanship.


Granted I know there also vacuum to account for so I did this as well.


The orange is where the fast idle stops when WOT and also vaccum included. I feel like it should be bottomed out at the red arrow, cause that's when it disengages the lockout, but it only goes there with my finger.

Thanks for the help and does anyone know the fuel line end sizes for the carburetor to fuel pump for 72 C10 350?
