Injector Pump

Thanks for all your responses, all this information will be helpful.I am not wanting to rebuild the pump unless necessary. I understand that everything else in the ignition system should be perfect before trying to diagnose a fuel injection problem. I found the points are very pitted with a burn spot so I have ordered a new set and condenser then I will attempt to remove the extra oil in the pump. The oil does not smell like gas so I don't believe there is an internal leak. O have read that any dirt in the system could cause a rich mixture so I would like to check the fuel filters and then make sure the thermostat is functioning. I have tried to find the model plate but have not found it. I assume it is a R1 model pump but not sure yet. I will post updates after replacing the points.
