had the vacuum advance go out on my TR4a many years ago, I could tell something
was wrong, and I eventually figured out it was the vacuum advance, the car idled
and ran fan, but made less power, and I think it was running hotter too, you
could probably adjust the static advance to offset this somewhat, but there was
a noticeable difference (if there wasn't I am sure I never would have figured
out that it wasn't working, or at least it would have taken a long time to
figure it out by a chance test of the vacuum advance unit. At the time I
didn't have a timing light to check how it advanced through the rev range and
throttle settings.</SPAN></P>
