Gas comming out of header

I've got a weber 38/38 and my jeep sometimes has problems starting in the AM. If I tap the gas more then one time during start up then gas spills out of the bottom of my headers during high idle. Then this morning after I drove 30 miles to work gas started pouring out after I had parked my jeep and turned it off. Anyone know what could cause this?

Carb needs a new inlet valve seat seal. (this is what closes & shuts off the fuel feed to the float bowl, when the float reaches it's up position)

This condition may not be so great for your engine. If raw fuel pours into the cylinders, it will wash the protective oil coating from the cylinder walls.
This will cause premature ring wear & oil dilution. Gasoline is a solvent of oil.

Thanks. If I get a rebuild kit, this valve seal will be with it?
