No kickdown linkage?

You must have had better luck then I
I ran thier throttle cable for a while and quality failed me rather quickly
The stud that mounted to the carb stripped it's threads, the cable actually cut a groove in the ferrule it ran through and eventually the cable ended up fraying and breaking

Mine is mounted on the same bracket as the throttle cable and making sure the cable pulls straight makes a big difference.
Every cable setup I have ever seen will cut into the ferrule's if it comes out off center.
