gas leaking out of the overflow tube is definately a float or float tang problem. if you are sure the tang on the float is adjusted probably, then the float may have a hole in it and it is no longer "floating" to shut off the supply of fuel. i'd remove it and submerge it in gas for a bit and look for air bubbles escaping and also see if it no longer floats after you release it from being submerged. if either happens, then replace the float.
running rich is an improperly adjusted air screw, wrong setting on the jet needle (long needle attached to the carb slide with a circlip), clogged airfilter or wrong jet (main or pilot) size. i'd try to find out the settings for these items and adjust accordingly.
hope you get it all sorted out and get this classic back on the road!

Hi and welcome to FixYa,
Almost always, your described problem would be the float needle not closing the inlet seat. This could be caused by a dirt, sand, contaminant, worn needle ends, grooves on the seat. Unfortunately, the only fix would be to pull down the carbs again and redo. Considerations are:
Good luck and thank you for using FixYa.

SOURCE: Float setting for BS34ss carb
I have a set my float to 22.0 +- 1.0 for a Mikuni carb.
To set floats, drain the carbs, pull the carbs from the bike invert and remove float bowl.
With the carb inverted, take off the float bowls. Take off the gasket. Use a vernier caliper or an accurate device to measure from the carb body to the top of the float block.
Here is are a couple of good sites about carbs and such.

you put it on the float base and allow the float to drop down and read the gauge where the float is read the top of the oppiste side where the float is hinged.
