Briggs 19G417 1181-E1 engine runs on 1/2 choke kind of?

Finally got the engine to start for more than a chug and die. If I feather the choke it stays running but it's like it is missing and as soon as it is slid to RUN it dies. Even got it to stay running at 1/2 choke but it was sputtering and what seemed like high RPM???

Has a new carb and am also wondering how many turns the mixture screw is usually in/out? Messing with that got it running this far but far from perfect.

This is all on a Coleman Powermate Magna Force 5000 generator.
