Mercury V6 2stroke carb cleaning Help

Hi can anyone tell me if a sticking carb float would stop the motor running all together, it was running after sitting all winter but only at idle or high idle but ruff. I then noticed fuel flowing out the bottom of the carbs when running, but now the motor will not run.. Anyone here removed carbs before to just check bowl floats etc is it hard? Any advice thanks..

I would suggest to check the fuel pump/supply system, is there a check valve in the system?? Running multiple carbs, a blocked float in one will only make it run rough on those cylinders the carb is on.

Thanks, i was thinking it should run still but now that you have said that, When I was pumping the fuel primer fuel was leaks out just like it was when running at a fast rate from the carb area, I was thinking it was just me pumping to much in or would this normally just fill up the carb bowls and stop once all are full?

One other thing since he motor will not fire now, more than likely no fuetl getting to the carbs, can you just spray fuel in to each carb from the filter side instead of removing plus and putting some in that way just to see if it is fuel starvation. Thanks

Not exactly the same but I had an issue with a Mariner 115 that turned out to need new float needles (early 90's engine). They were @£15 each. The tips were not seating properly allowing fuel past but it did start. Have you pulled the spark plugs out to have a look ?

You could have flooded it, its easy enough to do. As mentioned, whip the plugs out & spin it over a bit, dry the plugs or even warm them up a bit with a blowtorch before they go back in.
