Floats stuck. Take carb fully apart and clean it. Making sure to take out the needle jet and clean that and or replace it.

sometimes you can tap the side of the carb lightly to get the float to work unless it has trash or something in it but you still need to replace the fuel shutoff like mentioned and is best to take it apart for a cleaning.

If fuel is continuously flowing even after shutting the gas off, it sounds like a bad petcock in addition to the floats in the carb being stuck. Keep in mind that the float bowl holds a decent amount of fuel so even if the gas is off, it'll still pour out the overflow for a few seconds.

Take the whole thing apart and run it through a few cycles in an ultrasonic cleaner. Did that with my ‘05 carb, as well as 3 or 4 lawn equipment carbs, and it worked great. Harbor Freight sells the one I have for like $70 bucks. That, a 50/50 mix of simple green and water, and you’re golden. But I also agree with the Percocet change out as well if the fuel don’t stop coming out after a little while post shutoff.
