How very interested I was to read Maldwyn Jones’ letter in the December issue of MOTOR SPORT. My elder son and I used a TR6 for a Continental holiday in September at altitude 4,000 feet. We, too, experienced misfiring, black smoke from exhaust, lack of tickover, etc., all of which vanished when we were down to lower levels. I wrote to Standard Triumph about these defects. I received a typical “pass the buck” reply and I quote: “Our Export Service Division have been in contact with the fuel injection equipment manufacturers, Lucas Limited, regarding the difficulties experienced with your son’s car whilst operating at an altitude above 4,000 feet and we have been informed that in fact there is no altitude correction required on the fuel injection system.
It can therefore be assumed that the difficulty of misfire and excessive exhaust fumes at this altitude were possibly due to the vehicle running in an over-rich condition.” Why should it be so difficult to persuade the manufacturers that we, the owners, might be right?
