I think the fuel you see splashing on the throttle plate is the cause not the effect.
Check your fuel pump pressure. Is it stock mechanical or electric?
Your carb could also be leaking internally.
When the engine is cold, look down into the carb and open the throttle. Is there fuel sitting on the intake?
You could have a leaky needle and seat.
