Push pull cables. Just the cable not the control. They are built better and the cable is internal.
Google how to cut to fit and how to make your own ends. Although most will be available in lengths close to perfect.
Aircraft being the highest
Bicycle/lawnmower being the lowest.
Finding something in the middle as far as a sleeved cable is easy enough. This is one of those things you don't go cheap on. I have broken cheap throttle cables. Using electrical wire and a light foot to get home. Never again.
Sbc really tells us nothing. Several ways the cable can be routed, length, carb, and so on. If possible avoid bends. Lots of ways to do this.
Picture of your engine bay with aircleaner off and knowing what this is will give you better responses.
