Since I don't deal with mini-bikes and only claim knowlege of British motorcycles, I can only give you an educated guess based on general principles.

The most obvious possibility is that you have a problem in your carburator. The float is usualy the item that controls the flow of fuel into the machine. If the float or valved it actuates are not working properly, the fuel will continue to flow into the carb until you shut off the supply.

There may be even a little crud stoping the needle or valve from closing completely.

It's time to tear into the carb. and check things out. Maybe a good cleaning will do the trick or you may have to replace a couple of cheap parts within. I hope that is the case.
