On the rolling road at Aldon Engineering
Alan Rennie has always been impressed by the performance of his MGBGTV8, but just recently had felt things were not quite what they once had been. He had carried out all the usual checks, but that old sparkle was simply lacking. Was it the timing? - well with a 123 fully electronic distributor fitted, very unlikely. What about the leads, or maybe the plugs, even perhaps the carburettors? All checked out, so what was denying the car its legendary performance? 300109 More
