Leaks out of the tube coming from the bottom of the carb

If it is a plastic compression fitting you can tighten each one a little(careful not to tighten them too much cause they can strip out) Use a small crescent wrench with a back up wrench.
SOURCE: bike leaks gas from a tube between the carbs
Either the float is stuck or the gas set up sticking the float valve in the open position. The best fix is to take the carbs off and apart, but if you are not easy with that, sometimes Seafoam in the tank will dissolve the old gas if ti's not too bad
SOURCE: gas leaking from hose that is under tank that is not for gas flow
is it an overflow from the carb? gas will only be in one of 2 tubes and they are the fuel line from the tank and the carb over flow. unless you have an electronic fuel pump then tubes go from tank to pump to carb. if its coming from the overflow then you are getting too much fuel into the carb float chamber. you may have a sticky float. thy getting some Berrymans B12 fuel additive and putting double the doseage in the tank. run engine til hot then leave it to stand overnight. this should break down any gum/varnish that has built up in the system
has this been in storage thru winter?
SOURCE: carb leaking
You have a carb float stuck open. Turn off the gas and drain the carb. Next, turn the gas back on and sharply tap the float bowl with the plastic handle of a screwdriver as the fuel bowl refills. The goal here is to vibrate the float to free it up. If doing this process a couple of times does not free the float I would remove the carb and clean it with a spray carb cleaner. Be sure main jet is clear. Clean the air filter then re-mount carb.
Next Remove the water trap bowl at the bottom of the petcock, (gas valve). Dump it, clean it and re-mount it, ( not all bikes have a water trap bowl ). Install an inline fuel filter. Turn the gas on, wait a moment for the float bowl to fill with gas then give it a try.
How long since the carb was serviced? Has the bike ran properly since the service?
Please rate this solution. Thanks!
SOURCE: Gas leaking from bottom of carb on 90cc ATV
yes there is a tube that goes on it. It hangs straight down about an inch or two past the botom of the 4 wheelers frame. It is for a overflow of gas, which is usally caused by either dirt in the carb holding the float to high and allowing the gas to just run straight thru and out the bottom of the carb or a bent or maladjusted float setting. But since you said it just started, i would suggest this. I have fixed many and many bikes by simply removing the carb bottom and cleaning it with carb cleaner. It onlty takes a small piece of dirt between the float needle to keep the needle from making a good seat in the carb. Clean it well Please be carefull and keep the carb well away from your face as to not get any blowback of cleaner in your eyes(IT BURNS) This should fix your probblem
