Exclamation Generac 4000exl generator gas leaking through carb to airbox, help!

I bought the generator a few years ago and had no problems with it since then. now it wont start and gas is leaking from the choke side of the carb into the airbox. I thought that it may have been flooded so i took the carb off and drained the fuel from it only to have it leak again after a few pulls to start it. im trying to avoid buying a new carb so im hoping there is an easy fix. if not a carb is cheaper than a new one. Any help would be appreciated!

You need to take the bowl off the carb and clean the carb. The float is probably stuck down.

thats what i did today and the float seemed to move freely and everything seemed to be pretty clean , but it moved with the bowl off, could it be sticking when the bowl is on?

Could be, is there a dent in the side of the bowl? Something is allowing the needle to leak. The needle and seat may need to be cleaned.

Don 't soak the needle valve in carb cleaner. It's rubber tipped and will melt or deform.

Probably a common plug. If it's a chinese honda GX clone engine, a champion RC12YC will fit.
