Stihl FS111RX

Bought a real basket case of a trimmer. FS111RX. At first the thing flooded HORRIBLY. I mean it would be full of fuel with the first couple pulls on choke. Fixed that issue with a new OEM Stihl Carburetor. Also threw in an OEM service kit and Adjusted the valves and installed the gaskets. Now I can get the saw to start and run by holding down the throttle from initial cold start. It runs super rough, does not rev up, and as soon as I let go of the throttle, it dies. So it won’t idle at all. Any ideas? There’s also fuel inside the air cleaner vent hole past the tank vent… thinking maybe a bad fuel vent
