The fuel must get through the check valve that the float operates before it
can get to the needle/jet assembly. Fuel is only let through the fuel bowl
if it is siphoned out via vacuum into the jet needle assembly. Without the
engine running, there is no demand on the system so the fuel bowl should be
full and the check valve closed.
I'd clean up and replace the fuel bowl float and the valve assembly in the
bowl first.
