Question about Motorcycles
Lots of fuel dumps back into breather box while starting and when it starts if it starts if it does start it runs poorly
Off the top, I would say your carb float has sunk requiring replacement. Hard to tell much more since you dont say anything about make, model or year of your machine. You should take this motorcycle in for professional service.

SOURCE: fuel leak
Wait... fuel is pouring out of the crankcase breather? Are you sure it's not the carb overflow tube? The crankcase breather should be going back into your airbox or through some kind of filter. If gas is coming out of there DO NOT START YOUR BIKE. It means that gas has gone from the tank through the carbs into the cylinder and is now in your oil. Thinned out oil is the devil for bikes. Sounds like you'll need to clean the carbs and set the float bowl height and maybe rebuild the petcock. Check to see if any fuel is coming out when the petcock is turned off. If it only has on pri and reserve then check for gas in the vaccum tube.,,

SOURCE: fuel dumping
Sounds like a vacum issue with the tank, try starting the bike with the filler open, when you shut the bike off of no more fuel leaking then you may have a vacum issue with the tank. I have seen cases where the vent tube in the tank is clooged and it wont allow the fuel to return to the tank properly.
