Like the title says my kids lt80 is leaking alot of fuel from blower area, the motor turns over, but will not start. Also there is a hose from the rear end that isn't plugged into anything should it be? We bought the lt for Christmas present non running and at least now it turns over consistently. Any help is appreciated greatly.

 

Fuel is leaking by the float needle and filling the carb and motor with fuel.
Clean the carb well. Remove both jets and the needle and seat.
To eliminate this problem, get a simple on/off valve at the autozone in the lawn mower section. We could talk all day on why, but that's the fix on that.
FYI: the petcock lever should point down.

Running:: remove the spark plug, place a rag over the hole and spin the motor till fuel stops comming out. Replace plug and hold the throttle wide open till it cleans out and starts.

Without a better explaination on where that hose is comming from, I'm guessing it's a vent hose.
