Hi ...... Sounds like debris in the carb bowl, tap the bowl with a wooden hammer shaft and check to see if it's helped. If not switch off petrol at tank and drain carb. Retry switching on. If that fails take bottom of carb off and check float hasn't split .......... never seen one that has in over 30 years.

A picture would be helpful but if I were to guess the fuel filter fuel line would attach to the top/ middle of carb, the other line works as an overflow, dumping back into the gas tank or it may hang free. I think you can get away with a trial and error test. Hook it up the way you think and then try to start it. It will either run or not. If not then switch the lines around and then retry to start it. Hope this helps
Bikes with carburetors usually have a breather hose that releases excess gasoline. It doesn't connect to anything at the lower ende, it's a "dump" route. If it's it doing this a lot, it means the float(s) in your carb(s) are either sticking or set too high. This causes excess gas in the carbs, and the breather tube is getting rid of it. You have to take off the bottom of the carb(s) in order to check the floats. Look in a service manual or online for how to do this for your model.. and don't smoke while you're trying it!
I think your talking about an Overflow gas tube that keeps your enging from flooding from too much gas, your carb may need a little adjustment so you stop dumping gas.
Check the owners manual you should have got with the bike, if not check ebay there are loads available.
You will need to remove the two electrical connectors as well as the two pipes, one the overflow, the other the breather. Best to remove these first.
There is a safety cover that needs to be removed before you can release the main fuel plug. Once the cover clip is removed, the main clip needs to be squeezed at the release point (you should see the depress points), and pulled gently to remove. Best you have a friend hold the tank while you do this.
I found this to be a problem when I first removed the tank off my mt-03.
If its got floats in carbs, a needle and seat could be stuck open, or if somebody's been monkeying with it the float adjustment could be set too high allowing too much fuel in the float bowl and then it goes out the overflow tube.
