I got the drawing from Vans for the IO-360 throttle/mixture cable (drawing OP-22) which I did not see included in my FWF IO-320 kit. It has a bell crank to reverse the direction of the mixture which allows you to avoid cutting and making a big bump out in the cowl. Has anyone tried to use the vans parts on an IO-320? The drawing is a little difficult to tell were the bell crank pivot mounts and how that might be different between the IO-320 and IO-360. I have never seen that talked about here. It would nice to avoid the time in doing the trial and error mod to the cowl.
