john deere/ carb leak?

[sparkeycars]

Hi there. I have a 2001 john deere LT155 lawn tractor. The carb started leaking gas yesterday. I will start but you have to have it at half throttle to run. Gas is leaking under the bowel. I did not see any bad gas lines that have rotted or cut! Not an good engine person but it though a gasket or rubber seal has gone bad but i don't know where to start lookin for a bad gasket or rubber seal. It will run but will not idle. Gas just drips steady when the engine is runnin. any suggestions for me? Thanks
