    If you did a proper bench sync then your throttle cable is hung up and keeping the butterfly plates open. Throttler should :snap" closed and you should hear it.
    Few other things;
    Enrichment circuit(choke) is open
    Float levels too high
    Idle speed screw turned up too much

    Mixture screws should be 2 1/2 turns out to start

    Did you check the valve adjustments?
