22 HP B&S 407777 0607 E2 on Craftsman YS 4500

Mower would not run under a load. Changed  697722 carburetor with aftermarket carb. Fuel is filling the air intake. I can't find the exact throttle/choke hookup. Is there a spring on the throttle linkage that I lost during the change, maybe?

    Carb is not sealing at the needle and seat causing the overflow of fuel-  IE crap
    possibly holding the needle from sealing or just Chinesium junk.
     
    The is a very thin and long spring that goes around the throttle linkage.
    The solid linkage that goes from the carb throttle straight to the governor arm.
    The machine will run with it disconnected but will surge.

    Thanks. I just don't remember it when i was replacing the carb. There are 2 other springs present, a heavier governor spring and I think it's a throttle idle spring. So a third spring around the throttle arm. Thanks.

    Can you give me a part number for that spring? I bought a spring kit, not sure which one. At 10:29, he shows a spring.
