When Mx.{John H Maddocks - Chief Proving Officer} was trying 32-EX. in London under traffic conditions, he reports :- "Pronounced misfiring occurred on both A.{Mr Adams} & B. ignition when accelerating from low speeds. This was overcome by temporarily replacing the Lucas coils by standard " RR. taken from stock.
