Need some advice troubleshooting a Holley DP
I'm out of ideas on my Holley carb/fuel problem. I've got a 600 cfm, dp, manual choke and mech secondaries. The car ran fine up till a week ago. It started to stumble, got progressively worse then started konking out on the street, and hard to re-start. Pushed it home once (would you believe I got cut off by a pick-up while pushing!!) and towed yesterday. It acts like it's running out of gas. When it starts to die, I can keep it running for a little bit by pumping the throttle, but then it dies and may or may not re-start. I took it apart and blew it out with carb cleaner and then comp air, but it does the same. I have 6 psi all the time and when it dies, I pull the fuel bowl site plugs and they both look fine and when I pull the throttle, the squirters work good. I also let a sample of gas sit overnite in case I had some water..nope. What am I missing?
Any ideas would be appreciated as always while I'm re-charging my battery (the car and mine)!!
