Gas pouring out of the carbs means the float pin are not sealing in thus the over flow.
Go a little down thn .77in , best would be to bench set them.
Take a pipe say from the tank to the feed pipe of the carbs (best would be to remove the tank and place it higher on your work bench to get the gravity flow to the feed pipe of the carbs)
Allow the flow to the carbs and monitor the over flow, see which carbs over flow, remove the float bowl and reset the float and let it go a little less thn .77in, refit the bowl and retry the feed in and recheck..you will come to a point where gas wont over flow, open the bowl and see the level of the gas , it should be covering the jets, but remember that since you will have the float bowl out the gas will show low as when its submersed, the jet stem in the float bowl pushes the gas level up so dont get mixed up when you see the level low , i am sure you will be able to judge it for yourself.
I had the same problem in myYamaha(seca) XJ750R !981and finally managed to win over the problem going over it the way I explained.
Hope this helps! Good luck.

that would be either the float set to high or the needle and seat is missing an o-ring while you had it apart. Should look at getting a carb kit there only approx. 23 bucks and it would save you a lot of grief in the long run.

Well, a couple things may be wrong.
1) debris could be lodged under the needle valve. Remove the float by gently slideing the float pin out, the needle will either slide out with the float or remain in the seat and a pair of needle nose pliers will help to retreave it. clean the seat and inspect the needle valve for damage.
*note that even the smalles debris can keep the needle from seating so take care during reassembly*
2)depending on the type of carb cleaner used, and the exact type of needle valve in your carbs, the needle valves may have been dammaged during the cleaning. Some carb cleaners can "eat" neoprene or rubber components in carbs. It is always best to fully disassemble them before cleaning, if you are not confident in your ability, have a pro do it for you.
The solution for this is to remove the needle valve as above, and inspect the needle and float for damage. **If in doubt replace the needle valve**

You probably have a stuck float needle or a float needle that missed the hole check the leaking carb again. It could be a piece of dirt on just the one float needle or worst case scenario a sunk float(you have to test them by floating them in a cup of gas.).Note: black plastic/foam style floats are susceptible to saturation sinking when used in ethanol fuel (gasohol). If this happens you have to replace the float.
