Took my car out today and during the run I gave it a few hard runs through the gears. On my last run it starting trying to cut out on me and die and I had to nurse it back to the house. I Barely made it as it refused to idle and I had to keep reving it to keep it from stalling out. Once I got back I could smell it was a fuel issue. Took a look at the carb and I can turn on the electric fuel pump and the fuel starts poruring into the rear bowls. The linkage is fine and the butterflies are closed. It seems there is something wrong on the back end of the carb as the front is dry as a bone. Any suggestions where to start? I am gonna pull it tomorrow as Im somewhat familiar with Holley carbs and know just enough to probably get me in trouble. : )
