Help. 1965 running bad.
I picked up at 65 with the original 289 engine. The car would not stay running. I rebuilt the carb replaced the water pump, fuel pump, wires, cap, rotor, plugs, coil, and points. New fuel tank and fuel line as well. Has the stock 4100 carb on it.
Son and I started her up and she ran great for 5 min then that was it. Runs ruff and cannot get it to stay running. While she was running she was purring and sounded great. She was burning a tad bit rich but was running great. I am running out or ideas of what to do next. What can cause it to run like crap after she warmed up? This is old school stuff and I am stumped.
