Glad you got it running. Using a file will remove the thin platinum coating on the points, which will only cause them to pit. It's a great temporary band aid, but you really need to replace them.
Before jumping to the next problem, you should address the ignition side by doing a tune up. New points, condenser, set the dwell, replace the cap and rotor and plugs. Then you should attach a fuel pressure gauge to the fuel rail, this may reveal low fuel pressure due to a plugged fuel sock inside the fuel tank or the fuel filter itself or maybe both. Removing the vacuum line to the fuel regulator will simulate wide open throttle, which causes the fuel pressure regulator to not shunt fuel to the return line. With the vacuum line attached, and vacuum present, fuel pressure is reduced. If the car stay's running only with the vacuum line off, kinda tells me that you have a problem with fuel delivery. But, if you have the incorrect dwell angle, you car will also stumble when the RPM's raise. It's good to be thorough, so lets cross off the ignition side first. Also, you really need to replace the plastic fuel lines. With the age of this car, they are very brittle and is a ticking time bomb. They sell a stainless steel version that you should really consider buying. Best of luck |

I know the regulator is not adjustable on on the L-Jet injection but this one looks like it could be adjusted. |
