I used the "lawn mower" push pull cables on my throttle using the "wire grips" (see below) and they work great. You can attach a rod end bearing or a fork on the ends. I used 4 in my throttle run, throttle handle, carb, and two at the reversing arm. My left mounted throttle assembly (see panel photo below) is a dual lever assembly with friction lock and one handle removed, the long handle shortened, and a section of mop handle added as a hand hold, P51 style. Works great. Zoom in on the carb photo to see wire grip, rod end bearing, and wood washer to prevent a disconnect in case of bearing failure. The red knob on the panel is the locking mixture control and the black knob is carb heat.
