318 will not start

Yeah been busy just got the car Monday. I did confirm good spark and replaced the ecu and ballast resistor just to be safe. Also found the crack in the pcv hose replaced that. Maybe it is a stuck float then. Carb is a Carter 2 barrel. How would I go about checking for a stuck float? Tap the carb with a block of wood and hammer?
The needle and seat unscrew right from the front of the carb, where your fuel line goes in. Couple of wrench's, it's out in 30 seconds
