*Wow... Thanks Ralph. I hadn't thought about that. I did ponder
" carburetor *" for a moment, but not the float valve. In my paranoia I
immediately suspected foul play. I changed out the oil and did my mow
job, parked the mower. Then ran a length of black thread across the
garage opening ( no doors ) and check it periodically to see if anyone
had 'tripped' it. My next move was to be a trip to Harbor Freight and
buy a motion detect alert gizmo ($16.95). Then I'd fill my S&W 357 with
38 Sp shot shells and wait for my queue...

Adding a fuel shutoff would help. *You could run it out of gas before

As Ralph suggested, sounds like it could be the
carb float sticking. You can pull the carb, take off
the bowl and clean it. They have carb rebuild kits
available online, Ebay etc that cost typically $10.
They include new needle valves, gaskets, etc.
The gasket between the carb and intake is usually
not included, so get one of those too. Carb cleaner
and compressed air if you have it to clean it.
