My son just bought a '74 MGB which has had extensive engine work
done on it,
including rebored cylinders, hard valve seats, etc.
The engine rarely stops on it's own when the ign. is turned off
I have usually cured dieseling in Bs by making sure the butterfly throttle
valves are really closed when you release the accelerator. The idle may have
been set high when the engine was tight following your rebore; now it has
loosened up, it idles too fast, and will diesel when you switch off.
Hope this helps,
Paul.
