It started the other day when out for a run; as we neared home Little Willie began misfiring badly then, just as we got back to my house, she cut out altogether and would not restart.
A quick check revealed no spark so, out with the plug and in with a new one. Still no spark. Checked points - they're OK - checked timing - OK - now about to fit a new condenser, then we shall see. If that doesn't work, maybe the ignition coil is suspect.
The worst part is kneeling down wotking on the engine, then, getting up again. Ouch! My b****y back! Showing my age I guess!
