I'm completely at a loss here, I have a 67 newport with a 383, I drove it all weekend and it ran great, never had an issue. Monday morning I start it up to drive it and it sounds like I have a massive exhaust leak, and it smells like raw fuel. It cranks over and starts normal and idles fine, I verified that I don't have an exhaust leak, I checked all my plugs, they're not fouled, I've replaced my cap, rotor and coil, the points were replaced about a year ago along with the condenser, and all my plug wires are also good. Has anyone else had this problem? If so what was the fix?
