Wouldn't fret too much about the dry float height. Because, the carb doesn't really care about the "dry float height measurement" (which might or might not result in the correct fuel level).
What the carb does care about is the fuel level being within specs as determined by the clear tube test, which most manuals refer to as the service fuel level.
Would defer tang adjustment until needed incident to achieving the correct fuel level as determined by the clear tube test.
The specified dry float height measurement is supposed to result in the correct fuel level as determined by the clear tube test. But in practice, a "perfect" dry float height measurement often does NOT result in the correct fuel level as determined by the clear tube test.
When the delicate float mechanism was in as-new condition, unbent and unworn, the dry float height measurement had a better chance of resulting in the correct fuel level as determined by the clear tube test.
Nowadays, it's not unusual to find that the same identical dry float height measurement in every carb produces differing fuel levels in the carbs as determined by the clear tube test. And which necessitates readjustment of the tangs.
Good Fortune!

I just changed out the needle and seat assembly and the existing measurement I am getting is over 20mm. My question is does this 18.6mm measurement sound right to you? Seems my carbs must have been pretty far out of spec. I wanted to consult you before I start bending tangs. Thanks for the input, Keith
