Hey Bobcat, I'm having the same problem with my 650 DP.
Gas is weeping out just below the front vent tube when I hit the squirter without the motor running and not getting a good squirt from the primary. Upped the squirter size, pump cam, Same thing. I'm getting fuel behind the power valve also. Contacted Holley's tech to see if they had any porosity issues with there castings and they said - If you have your gaskets installed right you may have porosity. - So bottom line is they didn't answer my question or offer to help. I've been using Holleys for 40 years and I guess It might be time for a change. Good luck, Russ
