I have gas still coming out of my lower port carb on a Merc V-150 (1982). The gas is coming up from the bowls and spilling into the carb. So here's the question: if the reed block or reed valves are faulty, then what is the affect on my engine and carbs? Why is gas spilling out of my carb bowl and up into the carb? ...I have brand new floats, needles and seats in that carb.
