Martin, part of the answer may be in your question. If your TR6 has the
UE type of engine (lower compression, etc., and I'm assuming that TR6s
had these as did other U.S. spec. Triumphs), perhaps you're simply using
too cold a plug. The Champion N9Y or equivalent was for the older
engines; later ones used the N12Y or equivalent.
Try that and see what happens.
