Default 94 float height and float drop?

Could you guys explain float height and float drop. I think i understand the height measurement and where to adjust it but the drop measurement could use some discussion. I realise the other tab would be used for this adjustment but then I hear that drop is not that critical. Ford did not spec this but many of you knowledgeable Ford guys do think it is important. Can you go over this again for me including your opinions on the measurements? This wouod be forb the Holley 94. Thank you !

Default Re: 94 float height and float drop?

The float drop spec on a Ford/Holley 94 carb in my opinion is to make sure the fuel valve needle doesn't drop too far and possibly cock and stick. Just my opinion. Also prevents the float from hitting the bottom of the bowl.
It's measured from the gasket surface of the carb top to the bottom of the float. And the tab on the back of the hinge is used to move the float up or down.
A good spec for the float drop is 1 17/32". The float Level with the fuel valve closed is 1 9/32". That's only 1/4" of float travel, but plenty to open the fuel valve.
