Push tube length
I made sure the stick was centered and also that lever that both the big and small push tube connect to, I don't remember the name but I made sure that was centered, then I measured for the small control tube. That way you can adjust it some one way or another later. I never did have to adjust mine. Make sure just a little more than half of the threads are in the tube that way if the nut comes loose or you forget to tighten it the tube can not un-screw and fall off because the threads will bottom out of the other end before comming off. Safety...
