Waaaaaay too much fuel
I tried to start the 780 this weekend after it has been sitting for a while. For some reason, when I crank it, I can literally see fuel flowing out of the carb and down the throat. After it sat overnight, I looked and the carbs are completely full of fuel, which means I'm sure the crankcase is full of fuel as well. Any ideas why? Maybe a check valve is broken in the carbs?

Fuel selector valve was left in the ON position?
Another poster had a similar problem recently, turned out to be a stuck fuel tank vent valve, which pressurized the fuel tank when it got warm, forcing gas through the carbs into the engine.

Carb needles stuck open?
