Start with simplest first.. determine fuel or electrical. Pull the plug and see it it's firing. If it is I would squirt a little starting fluid or you can even pour a little gas (if you have something you can get it in there with) in the cylinder pop the plug back in and see if it starts, if only for a second. If it does I would remove and completely clean the carb. This was fresh water you inhaled I take?

this may sound stupid but it might actually be water in the gas tank and the carb just keeps sucking water in there and it won't run. I know this happened on my three wheeler and we couldn't figure it out. All we did was siphon most of the gas out of the tank and filled it up with brand new gas and it fired and ran perfect.

sometimes the pitcock on the tank gets clogged. Try starting it while it is on reserve. If you have spark and air, all you need is gas.
