slight misfire, help needed.
my car is a 1973 MK1 1600XL pinto, i have a slight misfire on tickover (when it does eventually tickover), above tickover it runs smooth, its as if its ticking over on 3 and half cylinders, i have replaced plugs, leads, rotor arm , air filter and points but its made no difference at all. any suggestions welcome cos its proper doin my head in now, Tony
'nostalgia.. its a thing of the past'
Best advice i can give you first is...... once you get it ticking over. Get a good pair of insulated pliers and pull the HT lead off each plug in turn.
As soon as you remove a plug you should hear and possibly see the difference. This will tell you if you are infact not running on all cylinders.
Cheers John

I know this is a long shot, but have you checked the tappet clearances?
