I had a miss on top cylinder replace coil and that solved the problem, The motor would the first time since replacing coil hesitated when I full throttle to take off after running full throttle I slowed down and then full throttle up and motor took with no hesitation, Thinking that maybe a little lean I adjusted the mixture in a barrel forward gear with prop off both top carbs and its running good just have to take it out on water for test run oh compression is appox 125 / 122 in top two cylinders.
