Hi I have had a problem with the car ( 1972 500 L ) cutting out after about 6 or 7 miles . I have gone through all the other things like tappets, fuel pump, filter in tank etc. Then I felt the coil which was red hot. It has a 650cc engine and I have one of the exhausts that bring both downpipes to the front to get away from the starter. I tried leaving the engine cover open and hey presto it was fine .I have now moved the coil behind the grill above the engine cover with some protection from the elements quite an easy fix. Has anybody else had this problem. It is a new coil of the correct voltage and it is wired the correct way round with contactless ignition .
