If 1 carb is leaking while the engine is running then try as plummen suggested but you might want to first drain the bowl. Remove the screw on the bottom of the carb bowl. After all the fuel drains out replace the screw and, while tapping the bowl GENTLY with the screwdriver handle, turn the petcock lever to the PRI(prime) position. Continue tapping until the bowl fills completely...give it about 1 minute. If it still leaks, you'll have to remove the carb rack and remove the bowl to see what's happening.tap on the bowls with screwdriver handle and see if it stops
Sometimes dirt clogs the needle and seat or the float will hang. Draining of the bowl and tapping while filling can often resolve these problems.

I'm guessing that the float needles are bad (oh I have 28mm on my 78 kz650) or the floats need to be adjusted. so how do I determine if its the needle and seat or just the float level.

Often a good cleaning will remove crud or grit in the float needle/seat interface and thereby restore proper function by allowing complete seal at the interface.
If deciding to replace needles and seats, should do them together as a new pair (both needle and seat). Should be available at Z1E.
Won't be able to accurately perform the clear plastic tube test for service fuel level until the leaking float needle/seat interface has been corrected. Because the level is measured where the fuel flowing into the floatbowl is stopped by a properly sealing interface.
Good Luck!

Well I got the leaking float problem fixed... but it still smokes like a train....
To play it safe, would sniff-test the crankcase oil for any gasoline odor indicating fuel contamination (and cause for smoking).
Good Luck!

When I put my bike on the side stand It leaks out of the #4 carb wtf? If its on the center stand it doesn't leak a drop.
Is it leaking from the overflow tube or from the seam between the bowl and carb body? If from the overflow tube, then it's likely that the bowl is still too full.
Plug looks rich. Did you pull the plug after riding the bike or was it just idling?

... When I put my bike on the side stand It leaks out of the #4 carb wtf? If its on the center stand it doesn't leak a drop... I adjusted the floats....
Exactly where is the leak from #4 carb?? Overflow tube? Bowl gasket?? Bent float bowl "ear" from over-tightening? Dripping from the pod (if so equipped)? Somewhere else?
What float adjustment method was used? Clear plastic hose test is reliable if performed correctly.
But the "mechanical-measurement-while-upside-down-on-the-bench" method is NOT reliable.
Good Luck!
