Intermittent hesitation high end

[duckmnn]

7.4 carb . Coming down on plane high side of rpms get a miss. Idle, no wake speed , low, mid range boats powers up great! 4 barrels opens and fuel spraying nice. New fuel pump and separator . Didn’t help. Going to throw money at full tune up cap rotor etc. Just seems weird high end rpm only miss shows itself . Any suggestions???

Tune up should do it. Don't overlook the wires
