Im still battling a lean stumble on hard acell, seems to be related to boat attitude, and how hard the launch is. Im running dual side mount carbs, on a t-ram, and believe that the jets are being uncovered, when the fuel is tossed to the rear. I have the taper cut floats, power valves blocked, am I missing something? This is not happening intantly, engine reaches full power 5700 rpms, then loose 900 rpm. As the boat lays over it recovers and goes, then repeats. The cycles get shorter, each time..... usually it lays down three times on a run.
