Varmit, I don't understand how the molecular density of the fuel would make any difference in the float setting. Idle mixture and/or jetting, yes, but wouldn't affect the buoyancy of the "bobber", would it?

Yes. The float is sealed so the air inside is probably at sea level when built more or less. So as you go higher up it should float lower. I have no facts, just talking off the cuff.
