Howdy, folks! I recently purchased a '72 Fury with 440, and I'm hoping someone can help me figure out why it doesn't like to start once it's warm. It cranks just fine, but I have to hold the pedal to the floor and crank it excessively, like it's flooded. I've had three different carburetors on it (for various reasons) with no change at all- so I'm assuming this is a timing or ignition problem? The car recently had a tune-up with new plugs, wires, cap, rotor, points, and coil. Any ideas? My best guess so far is that the new coil is getting hot? Or maybe the ballast resistor? Thanks!
