 Float height is really an irrelevant measure as it varies too much from float to float, fuel level is what you want to measure. Carb theory is not really my strong point, but the fuel level is actually a powerful tuning tool for getting transition and cruise right. It ties in with air correctors, e-tubes and main jets and can change "everything".

A wideband O2 sensor like the Innovate LM2 is immensely useful for understanding what is happening - if you are not measuring you are simply guessing.

John Connelly (sp?) from aircooled.net wrote a lot about it on the old Innovate Motorsports forum, unfortunately that forum seems to have disappeared.
