I have a 1980 tr7 with lucas distributor. It has the seperate amplifier. Do all of the distrubtors have the vacuum advance. Mine doesn't, or it is missing? Any ideas?

I don't know if a 80 TR7 would have vacuum advance or not; but certainly many Triumph engines of the smog era did not. Eliminating the vacuum advance reduced NOx emissions in the days before "3-way" catalysts.

My TR7 Haynes seems to imply that 1980 models still have vacuum retard, but no advance. But it's not very explicit on the topic, and certainly could be wrong.

Sorry, not much help, but it's all I got.

If it has the black box amp it did not have a vacuum adv.

Thank you everyone, I do have the black amp, so it never had it. John
