Fuel pouring from carb breather pipe

[miniracertim]

Fuel is pouring from my SV650's rear carb breather pipe.

Have checked float needle and it seems to move ok.

Did this a year ago after standing and cleaning the float chamber sorted it.

Is this the float sticking?

Or something else?

or the float has a leak.

Float seems sound - no leaks apparent.

Bike OK now - found fuel tank breather pipe partially blocked - could this be the cause?
