Actually, the way you have it- while crude- is actually not too bad as far as wear on the throttle shaft goes. That said, it's "unsanitary" appearing and the one spring behind the throttle shaft offsets some of the advantage of the forward-mounted spring. Not to mention using the hose to mount the spring- you need to use a solid mounting point rather than tie wrapping the return spring to the hose.
I would suggest you mount a bracket forward of the shaft as shown above and use the dual spring. You will need to improvise how the bracket is made and mounted, to have the spring in line w/the throttle cable (not at an angle, like if the spring were mounted to a small bracket attached to an intake mounting bolt) so the pull of the spring is in the same plane as the pull of the throttle cable.
