There are lots of suggestions for mechanical solutions for your problem,
however one of the leading causes is carbon buildup on the pistons. I would
suggest adding Chevron Techron into your fuel tank for a few drives. It is
advertised as a solution to reduce carbon build up in the combustion chamber
which is one of the leading causes of dieseling.

Totally stopped any run-on.

Did it prevent run-on?

The later model MGB used an "Anti Run-on Valve" which subjected the float
chambers 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.
