While in the middle of my 340 Dart project, I'm driving my other hobby, a 427SC Cobra replica. So the question is about the 780 Holley on the 429 in the Cobra. After sitting for as little as an hour or two, the car will not start because no gas is coming out of the squirters. I can take a screw driver handle, tap it on the front bowl a couple of times, and the squirters start working. After that, no problem until the next time it sits for a couple of hours. I rebuilt the carb about 10 months ago and runs great other than this. Any suggestions on what to check?
