I've just returned from an almost 2200 mile drive through France and Spain. Other than a terndancy to overheat in the high temperatures in Spain the car behalved impecably however towards the end of the drive three symptoms became apparent. A flat spot when acelerating at low revs, say from 1500-2000 rpm, a backfire on high speed overrun ie when letting off the accelerator at high speed and the tendancy to overheat more easily than ever before. I checked points gap, removed the plugs, checked gaps etc, all good around 26 thou, but noticed that all the plugs are very very light grey. Engine has done about 10,000 miles since complete rebuild two years ago which included carbs and runs like a dream lots of power and almost no oil use, about 2 pints on the trip total. Car is BJ8 phase II. Do the symptoms described look like it's running too lean?
