Sounds like it will be a lot of fun with your set up. Good looking plane too btw. I think it will still be a blast even if it hovers at above 3/4 throttle. I had a profile that was about the same and it was a a ball to fly.

I still cant help but wonder about the post to where the ones plane hovers just over idle! That is something else right there. I am willing to bet money that carb hits full throttle at just under half throttle and the rest is pushrod bind.
