I have a 84-86 mercury 75 hp 4cyl with 2 carbs. Engine runs idle and taking off but 3-4 minutes after plain engine starts cutting out like starving for fuel. I have changed fuel tank primer bulb all fuel lines fuel pump rebuild carbs and changed plugs and wires and one coil. But still cuts out, pumping bulb does not help and compression is 103 -110 on all cylinders. When engine starts cutting out i can pull back to wake speed for a little while and then take off for a while before acting up again, if engine cuts off i can put in neutral and starts right back up. Need advise where to go from here.
