I have had the carb stripped and reassembled on my 1971 2000 sc manual (series 2) and the engine tuned / timing adjusted by my local workshop, and although the car now starts, runs and idles much better, it pinks alot, even in 2nd and 3rd as soon as the car is under load. The chap that did the tuning has alot of years in the trade, works on all sorts of old cars etc, though he is not a Rover P6 specialist, and he recons that retarding (?) the timing would help, but performance would suffer. Altrnatively he suggests leaving the timing / tuning as it is but using a fuel additive, like Castrol Valvemaster. Can anyone confirm that my best course of action is to use the additive, as I do not want to compromise the engine performance by retarding the ignition timing if I can avoid it; performance is just adequate as it is, the car having covered 110,000 miles on the original engine, and without a rebuild or major work. Cost of the additive is not an issue for me as currently the car is my 'second' car, basically a hobby, and does not get used much.
