Lucho, with the carb bowls off, flip the carbs upside down so the float is compressed under it's own weight. With a ruler and no bowl gasket on the carb, measure from the gasket surface to the top of the float. It should be around 22mm.
Or, attach clear hose to the drain on the bowl and with the carbs fully assembled open the drain screw. Fill the carbs with gas and measure how far up the fuel goes. It should be about 2-4mm below the top of the bowl. If you need to make an adjustment, drain the gas, remove the bowl and bend the tang in the appropriate direction to adjust the height.
