Some weeks ago whilst giving my neighbour a lift home from work in the special (he'll never ask again!) it developed a misfire at low revs, gradually worsening over the 20 mile journey. The next morning a quick check showed that the points gap had closed up to almost nothing. I reset it but the car wouldn't start. There is no spark at the plugs.
I've changed components one at a time, starting with the condenser (2 different ones), then coil, distributor cap and leads, points and rotor arm but still no spark. It is a 12v neg earth system and I am getting 12v at both of the low tension wires to the coil. With the ignition on if I flick open the points I get a spark across the points. All the replacement components were known to be working when I stashed them in the boot years ago.
What am I missing? could there be a short circuit in the distributor base plate? I know this should be basic schoolboy car maintenance but I'm stumped! Any ideas?
