[TR] TR6 throttle linkage with vacuum switch/valve?

[Greg Lemon]

My TR250 is stripped of it and I put on earlier Stromberg carbs from a TR4
or 4A, which are much simpler.  It runs great.  I believe the valve in
question was part of what I call the "push me pull you" vacuum advance and
retard arrangement on the TR250 and early TR6 (the distributor also had two
vacuum diaphragms) I have the remains of this system including the valve in
a box in the basement.
