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 have found that that the slower the idle the less run on, probably due <b=

to less fuel present.<br>
In a round about way my question was probably which idle technique gives <b=
r>
a leaner mixture? Maybe at a specified idle speed the mixtures are the <br>
same.<br>
Since American cars of the 70&#39;s used idle solenoids, I am thinking I <b=
r>
could put on a solenoid for the idle with ignition off. When ignition is <b=
r>
off the throttle blades go completely closed. Combined with a low idle I <b=
r>
might be less irritated.<br>
