SOURCE: carb and valve adjustment
Presuming that the carb is clean !
It seems that you have either set the float level incorrectly, or allowed the needle to become jammed. The float bowl should a little less than 3/4 full of fuel when the fuel is shut off by the needle and seat.
Check that the needle and seat are working correctly by blowing in the fuel pipe, and then closing the needle by hand. Check that the flow is stopped when the needle is fully raised.
The needle and seat do need to replaced from time to time, but generally last well.
If the needle and seat work, then look at the float level.
Further check to see that the floats are not filling with fuel. If this is the case, then the floats will have to be replaced as most repairs are only temporary.
When the floats are fuel logged the needle will not be raised and fuel flow to the carb will be continuous.

adjust the floater of your carburator give at least 2mm space on the top of it when you lift the floater so it will not overflow.

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
Let me know

change the needle and make sure its jetting right, check the floats if it is operational. '90 to '95 carbs are compatible, so if you are planning a replacement, you may use those
