Fuel dribble in Down leg booster...

Today I took my 850 Proform carb off of my 422 small block. Totally disassembled it and cleaned everything with carb cleaner. I used compressed air to blow out every orifice in the metering blocks, I also removed the airbleeds and cleaned them like new. The lowspeed idle screws were removed and cleaned. After cleaning everything and reassembly I checked and adjusted the front throttle blade and made sure there was .40 of the transfer slot exposed. I base lined the 4 idle screws at 1.5 turns out. The engine fired right up and was running crisp, I checked the float level and it was almost spot on, a slight wiggle on the fender is all it took to spill over. A slight kick open from the rear barrels got it idling at 1000 rpm. I could smell the tune.. Crisp and fresh..

While slightly actuating the throttle, i noticed the front left booster dribbling fuel ever slightly.. Did I miss something???

:New plugs and fresh oil as well. Plugs look a little fat but still tan. Lots of idle time today.. Yesterday did a cold compression check. 110 psi on the first crank 150 psi on the second and 185 on tbe forth.. All 8 are the same.
Tomorrow's plan is Valve lash.
