The Lectron carb cap is drilled and tapped to accept their cable adjuster. The one that came with the carb is a brass one same as the image below.

By captive ends I was referring to the MotionPro T3 cables. Instead of just having a cable that drops into the sleeve, they thread directly into the carb, and directly into the throttle housing. A much better design imo.
The stock cable I am using has the 45 degree bend/sleeve at the end. This slides down into the lectron adjuster, however it doesn't take much of a tug on the cable to have it start lifting out (and raising the slide with it).
