MinnFlyer's idea is good. Works well with solid wire pushrods.

In the kit, I include a cable-in-tube type pushrod. For four-strokes, I like to lash a connector, facing backwards, to the cable. You can use a nylon clevis or nylon ball link, secured with wraps of thin copper wire and epoxy. You can stiffen the cable where it is exposed (not enclosed by the tube) by soaking with thin CA, if necessary.
