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?
