Your problem is most likely either vacuum leak as was suggested or the choke plungers aren't fully closing. It's not going to be mixture screws or pilot jets. The idle circuit doesn't just supply fuel at tick over it contributes fuel up to about half throttle but the % of total fuel that it contributes gets smaller the further you open the throttle. There's a graph showing it
