Ball link is 13-13.5mm from center of servo arm. Engine is still a little on rich side. I have been gradually leaning it out. Engine has 9 tanks through it. Rpm seems to pretty good but I don't have a way to check it yet.

I will try adjusting the ball link on the t/r and see if that helps. And I will also try dropping the gain down in the radio from a 100% to 80% or so........Thanks!!
