Flooding through the air filter housing

Sorry for bad technical english but hopefully it's clear enough:
I faced a massive gasoline flood through the air filter casing. And even running "poorly" and felt like overrich, will it come only for that the floater's needle doesn't close the gasoline to enter the carburettors even the cup is full? Where does the gasoline have the access and comes to the casing?

Another issue: What are the connecting hoses needed between the two carburettors? Is it only venting? And if they are in bad condition, what might the sympton or result be?

Thank you all for helping.

You may have a stuck carburetor float. It only takes one, the other may be fine. If so, there may be gasoline in the oil also (it leaks past the pistons). Remove spark plugs, if one is wet with fuel, that cylinder has the stuck float. It seems to happen a lot.

Yep. Tiki's got it. This has happened to me.

Your fix is to remove whatever gunk is plugging up the float needle. Some have tried reverse spraying stuff up there, but you may as well pull the carbs and clean the system. Blow the fuel hoses clean and make sure your tank filter is working. You probably either have gummed up float needle/valve or some trash that is preventing the needle from closing. Last time it happened to me it was a paint fleck from the petcock that fell into the hose when I was reattaching the tank.

Thanks for advice.

I also looked after older questions and answers and found a lot of valuable info from those.

Until next time...
