Need Assistance: 1971 Dodge Dart 318 – Throttle & Shift Linkage Setup

The first thing I see is, you need a sprAng in the front of the slot on the kickdown linkage to assure it returns to the pin in the carburetor. Not a gorilla spring, but just tight enough that it brings the linkage back to the pin every single time.
He has one on the kickdown already though ??
