I finally got all my linkage parts that I need and it still don't go together right. I think I have the wrong Throttle rod lever. (I think that is the right name please correct me if I'm wrong) this is the best pic I have if you look it comes out and steps down im pretty sure it needs to go up. I'm pretty certain its not on upside down the round side goes down and the D side goes up correct? Do they make different style levers?
