Contact points for 1920s–1980s classic cars
Contact points (contact breakers) open and close the coil circuit every time a cylinder fires, which makes them the busiest moving part in a classic ignition. They burn, pit and wear, and the gap drifts, so the timing wanders and the engine runs rough or will not start. Basis stocks contact points for cars from the 1920s to the 1980s.
Replace the points together with a new condenser, then set the gap and check the timing. Set the gap with a feeler gauge to the figure in your workshop manual — it varies between engines — wipe the contact faces clean and put a smear of cam lubricant on the cam.
