I doubt the hose is related to the current issue.
Sounds like your carb is totally flooding out.
Remove the float bowl on the carb, let a little gas run out of the carb and then work the float up and down to see if the fuel stops or not when the float is up.
If the gas does not stop when the float is pushed up with slight pressure, the carb is dirty or has a bad valve seat.
If the gas stops, your in luck. Clean the bowl really well and put it back on.
Remove the spark plug, position the plug wire where it will not spark on anything (also turn ignition off), and crank the motor over to clear the cylinder. Replace the plug with a new one and give it a try.
Check your oil level to make sure it is not over filled. Gas CAN sometimes go past the piston rings (called washing) and collect in the crank case. This will lead to a blown motor and possibly a BLOWN UP! motor.
Good luck, Keep us posted.
