I'm having all sorts of trouble with the mixture control linkage, in that it rubs on the inside of the bottom cowl when in the fully rich position.
I tried machining the control arm down to suit a bolt one size shorter, and I also adjusted the angle of the arm on the servo body, but there is still contact. I'm thinking I might have to cut a hole in the bottom cowl and fibreglass in a small "bubble", to accomodate the mixture control.
