Everyone I've got a 1986 75 hp 4-cylinder. I took it to the lake this evening and it was running out of gas at high rpms. I went and pumped the bulb it ran fine at top end when I quit pumping the bulb it would start to die down? I've got fresh rebuild carbs,clean fresh gas,new gas lines,new inline filter,new waterpump and plugs and plug wires? (?FUEL PUMP?)
