Leaking carburetor
I have Holley 670. This morning, i recheck the primary bowl level and the secondary bowl level to double check before adjusting. I also Replace a new gasket on my Gas cap and disconnect and reconnect the tubing of egr solenoid for better routing. I proceded to Turn on the car and it Choked, like if battery is failing. Sound like the engine was stuck and not turning at the beginning. After few attempts, finally came on, and it has rough idling. It doesn’t stay on unless i am on the gas, otherwise is stalls.
I noticed that there is a fuel running along the secondary diaphragm rod with engine off and gasoline odor is pretty bad
I am not sure if I damage something, but I only check things, nothing else. Any recommendations? any help is appreciated.

Re: Leaking carburetor
If your particular carb doesn't have the "blowout protection" option, your power valve may be toasted.
CW on the float adjuster nut lowers it.
