Engine goes right to full throttle/advance

I have a 66 dart with a 318 four barrel. I started it for the first time yesterday and it ran good. Started it this morning and it went straight to full throttle. Looked in the carb and there was lots of raw gas. I took the bowls apart and checked for sunk floats ,float level, inlet seats everything looked OK. started it again same thing. Even when bowls are empty it revs right up. HELP!!!!!!!

Please.
