Vadim's car was getting bad mileage prior to me richening the mixture one
full turn. His car has Strombergs...not SU's.....the plug we pulled looked
like it was burning pretty hot....that's why I thought we'd try to richen the
mixture a little. I've yet to see a TR6 sparkplug that I thought looked like
it was running right....every one I've seen thus far looks VERY lean....with
the electrode almost completely white.

Yes, this is correct....the TR's with Vacuum retard really hold back the spark
until 4 ATDC....we checked the advance and it's working properly....his is the
mechanical advance type....as opposed to the vacuum advance as fitted to the
early models.
