Another way which works well and will accomodate a much greater missalignment is to just run the pushrod out past the throttle connection, bend a U turn in the wire and come back to the throttle all lined up. This does require that you have a metal end long enough for the bend to be threaded into the nyrod at its exit of the firewall. This works very well with 4 strokes where you have to clear the fuel tank with the control rod yet get back to the throttle positioned inboard and very near the firewall.
