- I would like to start an on-list discussion of octane, timing and performance. I have a stock 1971 TR6. I currently run premium gas, which is what is recommended. With all the vacuums, etc attached I

- I'm surprised at that ... with the lower compression, more modest cam, and poorer breathing, I would have thought a stock US-spec TR6 would run fine on regular. So your vacuum retard is not working
