I had dumped out last years gas and used it in the mower. I have run through a few tanks of gas since the carb rebuild with no adverse reactions.
toojeep4u Dont worry about those guys. We get our fare share of blasting from them too. It just means you are now part of the family and they love you!!
As far as your carb(s) go , You have 4 carbs because you have a 4 cylinder engine which is derived from the first Ninja motorcycles like the one you saw Tom Cruise ride in the movie Top Gun.
I just re read your post and you do indeed have dirt or debris in your carbs causing fuel to leak out those hoses.
You need to do what SSIF said to do and look for dirt or tiny bits of debris in the gas you drain. You can check that all is well again by turning you petcock lever to PRIME and wait. There should be no fuel flowing out of those tubes. Dont forget to put the petcock back to RUN. You may have to drain, blow and refill a couple of times before the over flow tubes stop leaking.

I'd suggest to drain the bowls and blow down through the fuel line with some compressed air, the refill the carbs and see if the issue is settled. Feel free to email me also if that doesn't get it solve the issue. Steve
