Scooter Dumping fuel out of overflow??
I have 2 hyosung scooters that are dumping fuel out of the over flow tube. Cleaned the carbs, cause that would be a float sticking kind of issue? But! It is still dumping fuel out of the overflow... any ideas? Only happens when I crank it over.

If the float needle is worn it won't stop the fuel even if the float is working. Check to make sure it is a perfect little cone...

It is... It's a brand new carb.. put I drained the gas out. It sat for a year. I put fresh in just a week ago with some seafoam, and it just poors it out like nothing. :/

If the floats aren't sticking, I'd say it has to be the needle valve.
Did you try tapping on the bowl when this happens? |

Got the fuel to stop pouring out of the overflow. Just has running issues now. Doesn't idle, acts like it's not getting fuel. If I cover 2/3 of the air intake it will kind of choke it and run ok.
