As above, still got this juddering problem with my MK2 Fez. Basically, it's had a new Rota arm, new dizzy cap, new double silicone leads, weber carb cleaned and put back on and set up, new spark plugs (about last year) and the timing is bang on. Now when I put my foot down you can feel it blocking, then it judders. Now I've been told it could be the spark plugs need changing or the coil. But also when I put my lights on, the revs dip slightly and the clock light gets dimmer so could this be the alternator? Any advice would be brilliant!
