Here is a quick video of how easy it is to set up a throttle cable on a go kart. I have used Harbor Freights Predator engines a lot and for the most part they are easy to set up and if you take care of them by doing maintenance they last a while too. All small engines have the same setup though some have different linkages and cables your goal is to open and close the throttle. Good luck!
