Well, I don’t think J8 plugs would cause the engine to die on acceleration, perhaps one of those plugs is defective….
The timing isn’t really adjustable, but certainly check to see that the mag plate is moving freely and opening the carb butterfly properly…
What kind of boat is this engine on and how is the boat loaded? Too much weight in the stern will cause the engine to struggle trying to plane the boat off. Is this engine new to you? If not, how has this rig performed in the past…Post pictures of the rig, perhaps a video of the engine struggling to get to WOT….
