On the subject of Moggies - anybody know why mine has a tendency
to 'run on' for a few seconds after the ignition has been switched
off? Somebody told me it was to do with the unleaded fuel - she's
originally a leaded engine that the Morris Minor Centre in Bristol
'unlead-ised' with the aid of a 'magic' thingy that fits in line with
the fuel - apparently they've been fitting them for 20 years..

And ripping people off for 20 years then too.

A complete con. Tin pellets in a black tube. Tin isn't soluble in petrol to
start with and even if it was it wouldn't do anything constructive. You're
running OK on unleaded because the valve seats are hardened from years of
use and the engine isn't in a high state of tune. The black tube is doing
feck all to help the situation. A series engines tend to run due to
combustion chamber heat which is why the A+ SU carbs had a fuel cut off
solenoid operated by the ignition switch.
