I can somewhat agree to that....is something other then fuel creating it to hydrolock IF......the fuel plunger fails?

Than not the purpose the fuel solenoid on the carburetor. Now the float needle valve and seat can cause fuel leakage. But fuel solenoid is there only to block the main nozzle so the engine starves for fuel and quits.

To explain it fully
1) EPA decided that mowers must meet the same hydrocarbon emissions as cars
2) Overflow & float bowl drains removed , not that many mowers actually had them
3) float bowl vent moved to a hole near the top of the engine flange
4) solenoid fitted to main jet .
5) manifold & carb required to slope into the engine so any spills go into the engine & not to the atmosphere
So when the float bowl needle valve fails the float bowl fills to the vent hole then the fuel fills the vent tube and pours out the end onto the manifold .
From there it dribbles down the manifold & into the cylinder
next time you have a carb apart blow some goop through through all of the holes in the body and see for yourself where it comes out .
Then you might understand what is happening .
