1972 Mercury 650E 3 cyl carb floats

What would the performance symptoms be when the float valves have failed. Seeing fuel spil into the carbs when priming with the bulbs is certainly a symptom. But, what would one experience in performance? e.g. failure to start, stalling, etc.?

Pour a lot of Premix into the carbs, under various operating conditions and watch the results.
