Have a question. I have a 1987 mercury cruiser 170 hp 4 cylinder 3.7. When the boat sits for awhile i can crank it and it will run for a bit. then after i prim it will start and stall out like it flooded. i look in the carb and its got fuel siting in the barrel. then in netrual it still leaks fuel into the barrel. Does this mean its time to rebuild the carb. it does this even if it push the throttle button or just push the shifter forward
