The TR 6 (circa 1974) had a solenoid valve that dumped manifold vacuum when=
 the ignition switch was turned off.

The later model MGB used an "Anti Run-on Valve" which subjected the float c=
hambers to manifold vacuum when the key was turned off. I  would think one =
could be installed on a BJ8 without too much difficulty.

I already do the dump the clutch technique.
I have found that that the slower the idle the less run on, probably due
to less fuel present.
In a round about way my question was probably which idle technique gives
a leaner mixture? Maybe at a specified idle speed the mixtures are the
same.
Since American cars of the 70's used idle solenoids, I am thinking I
could put on a solenoid for the idle with ignition off. When ignition is
off the throttle blades go completely closed. Combined with a low idle I
might be less irritated.
