Distributor refresh gone wrong

I'll try to keep this short... Early 80s, Our 1st 67 notchback, 225 slant, showing a lil over 86K miles, ran but not great. Rebuilt carb, new fuel filter, adjusted valves. New plugs, wires, cap, rotor, points, condenser. Still didn't run perfect as I wanted. Intermittent constantly changing stumble. I finally discovered the distributor was worn out. Dwell all over the place. Reman'd distributor was like dipping the old girl in a fountain of youth. Ran absolutely perfect. That dist' included points, rotor , etc... all ready set up. Drop in, set timing, done. Good luck with yours
