thanks for the reply lads, I'm not after huge power just to free up Abit of power really or in fact bring back lost power! The carb apparently was cleaned and reset just before I purchased the car. Is there any direct replacement exhaust/intake manifold that would fit and be a decent upgrade? Or air filters or anything like that? Also to answer the question above I have no idea what plugs are in there but should I get some specific ones? Thanks
