The way I'm reading this is that your carb is leaking from the accelerator pump squirter when it's running? If that's right, there is a check valve/ball in the float bowl that's supposed to come unseated when you accelerate. Maybe some crap under the ball that's allowing fuel to dribble thru the squirter. That's where I'd start looking. Possibly the retainer for the ball has come loose.
