Every year I go to a local "Dino knowledgable" gas station to get my inspection sticker and the old guys there (yeah I'm one too) comment that my Dino is one of the best tuned cars with carbs that they see, makes me happy! Seriously though, it's a concern that the number folks with the knowledge and experience is slowly shrinking.
The solution is DIY, not so difficult. You just have to make the effort. Not only, once tuned they (or it) remain in tune. Regards, Alberto
