Depends on how well the float was made to OEM spec.
After you put the floats in, fill the carbs with fuel while they on a bench. See if the floats stop the fuel when the bowls are full.
Then take a clear hose that can be tightly secured to the drain line at the bottom of the carb, and bend out upwards towards the top of the carbs. Now open the bowl drain screw. The fuel will fill the clear tube as the bowl empties. Keep adding fuel to the carb until the float stops the fuel. The height of the fuel in the clear tube is the height of the fuel in the bowl. The measurement in MM from the fuel line to the top of the carb bowl is your fuel height. Look in the manual to see if that is in spec.
