GRB, note you are also missing the anchor fitting that has to attach the inner wire of the speed control cable, to the speed control lever on the governor: see green circle in picture:

Sometimes a cable with a single-wire inner is used, with a Z-bend in the end to engage the hole in the lever, or sometimes a more complicated gadget with a grub-screw, and a pin going through the hole in the lever. You can get something suitable from your local mower shop.
