Setting Floats

Well see what you do is measure with the carb upside down the distance between the carb base and top of float with a micrometer. Then adjust the float to the required hight... 20 to 21.5 mm.
 
from where the bowl gasket would sit, take it out, and measure to the highest point of the float itself, while holding it at a 45 degree angle, so the tab just touches the pin in the middle of the float valve....................
