Bowl float level 1975 Honda XL 125

[spindr123]

How critical is the bowl float level adjustment in a Keihin carb on my XL 125. I have replaced the float with a new one, along with all jets, and it measures off by 1 mm on the two sides of the float. Manual says 24mm is correct height. When one side measures 24mm, the other is 25mm. Float is the original type, soldered brass round float. Should I get another float, or is this common with this type of float. If I stay with the current float should I set the height at 24/25mm or 23/24mm? Thanks.
