Craig,
I thought the late 180B control was an air bleed to lean of the mixture and
hopefully prevent run on but I am open to correction here.
Craig Haywards engine runs smoothly!!! with no ignition on. Some one had
actually put a step up idle solenoid X auto trans model on the throttle
shaft to allow idle with ignition running. This would allow the throttle
plate to fully close when the ignition was turned off.
This is the only way to stop it short of a clutched stall!
Very cold plugs (NGK B10EGV) Platinum race plugs, actually improved the
performance. It also made the engine run smoother with less pinging. The
plugs do not foul at all. I guess due to the increased combustion
temperatures. This engine has 210 PSI comp per cylinder.
Cheers

Errol the run-on you described is likely due to the engine still sucking
fuel into the combustion chamber when there is enough compression and
heat or possibly a hotspot/hot plugs to combust the fuel creating a
rough idle with ignition off. What carby did it run?
I know of an L20B with almost flattops that has this same problem with
SU's, that runs too much CR. My 910 Manual shows the late model SU's had
a solenoid to the fuel bowl breather that closes and stops fuel being
sucked in when ignition is off. I think the late stock L18 carby also
has such a device.
Craig.
