I needed to do some work in order to get the throttle linkage cables working. My problem was connecting the dual carb cable which was too short to reach where I wanted to mount my throttle lever system (down by leg).
Below is a picture of the throttle lever I was working with.
In order to get this to work, I created a cable junction between the dual y splitter that was connected to the carbs and the extension cable connected to the throttle lever. Below are some pictures of this setup but be warned this will get replaced later after my initial test trial at the airport 🙂
