As the manifold heats or cools, it grows longer or shorter than the shaft, so the edges of the throttle plates are pushed into the sides of the throttle bores. This causes drag and greatly increases wear into the sides of the throttle bores. 3) Due to production tolerances, we find that in most brands of manifolds the throttle shaft bore in the front runners rarely lines up exactly with the one in the rear runners.... this puts the throttle shaft in a bind. 4) If the throttle shaft has a slight twist in it, the front throttle plates are open slightly more than the rear ones. Without the Spring-Screw link there is no way to correct it.
