Stumped and Frustrated with a Holley 670 Hesitation

I had a Holly act all weird on me like that. I took the rear bowl off to find the float was filled half way with fuel and had a hole in it..... Super sporadic miss is what I had until I put my foot to the floor.

Interesting! I think this may require me to take the carb off the car and give it a good once over.
