Yep, happened to me on a one year old rider (18 HP Briggs).
Fortunately so much gas poured in that it hydro locked and clued me in
rather than running with a crankcase of diluted oil. The starter would
grunt but couldn't turn it over. Mucho fun draining everything (no
convenient gas drain), no shut off, crankcase full, cylinder full.
Touchy part was pulling the plug and hitting the starter to empty the
cumbustion chamber. I made sure the plug was well shielded and not
grounded. Installed a shut-off after the clean-up. Just have to
remember to shut it off when finished using.
