how to check a float

RR, if you have a Nitrophyl float, (epoxy foam) you need a new float to first weight it to get a base line, and I am sure the density of the material would change from batch to batch when made. Back in the day, I checked the float very first thing pulling it out of the carb by using the back side of my fingernail and gently pushing a lower corner of the float and I if see wetness I change the float. Nowadays I just change it, if I can get a brass one all the better. I suppose if you wanted, weight the float get your number, then submerge it in fuel for a length time and then recheck.........
