I concur on the stuck float which could also be some crud holding the needle
valve open that cleared itself, and hopefully won't happen again. In the
meantime, you might do some reading up on your particular carb, and maybe
pick up a needle valve/float kit and replace (should only be a coupla
bucks). I had a similar (occasional) problem with my 4bbl last season. I
installed a fuel line shut off and ran the carb dry before storing for the
winter assuming that maybe this year I'll be replacing the needle
valve/float. This spring I topped up the carb through the vent with cleaner
and let it sit for a while, then turned on the gas and started it up (all in
the laneway using the muffs/garden hose). For what it's worth, no problems
so far.

I have read that shutting off the gas if the float sticks, running the carb
dry, then tapping the carb *gently" with a hammer might free a stuck float
(dunno if that would apply with an electric fuel pump) ... but hey, if it
gets you home :-).
