This whole conversation is scattered all over the place WOW!!

This is a 1979 CB750 .

The carbs should come last in the tuning up process.
Of coarse the gas leaking is an emergency.
QUOTE: "the gas is kind of rosy red like rust"

Take the tank off and CLEAN it. IF it needs to be sealed do it.
I recommend Caswell's tank sealer with one can of white colorant from tap plastics.

As far as the float valves... if it was me I would remove all of them and throw them in the garbage can.
End of that story.
Then get 4 brand new valves WITH seats and install them. Then set the float with a float gauge like the manual tells you. 15.5mm or .610 thousandths.
QUOTE: "I have even adjusted the tangs on the floats slightly."   Just set them to the specifications in the book.

WHEN YOU PUT water in the fuel line that means ANY WATER left in the carbs anywhere means all of the water would have to be removed. Even ONE drop of water can keep the carbs from working right.
GAS and WATER do not mix.


Now ALL the water MUST BE REMOVED from the system. That means the carbs will have to come off for cleaning.

You know i do not even think you should be working on this bike. For your own safety .
STATEMENTS like: "and they're pretty aligned with the valve cover surface as they should be. They're maybe a few millimeters off"  I want to tear my hair out.

LIKE I said all issues with the ENGINE must be done correctly before the carbs !!!
