Crappy idle, misfire on one cylinder.

Was it running fine before the distributor rebuild? Swap distributors would be the first thing I'd do if the previous statement was true. If it cleared up then I would send it back. But FWIW its more than likely the points. Local autoparts store used to have points/condenser kit where the condenser was made onto the point plate and they were great. Never had an issue with them. Blue Streak was the name but I wanna say it was owned by Standard Motor Ignition or Products..
