repair

I have a Briggs & Stratton 5 hp DR weed eater that will start with starting fluid but will not keep running. I took the carb. off and it was clean inside. I blew out the port holes, put it back on and fuel leaks out of a small hole where the air filter plate bolts on to the carb. there are two holes, one on each side of carb. air intake but fuel only comes out of one. Appreciate any help---Cambre
