L28 engine fuel problem

When you turn off the ignition the engine still runs and coughs and splutters for about 5-10 secs, it doesn't do this all the time but it is a pain in the backside, can anybody offer me some advice on what is happening and how to fix it
many thanks

id be looking at Wrong heat range spark plugs, have they just been changed?
Incorrect idle settings
Timing wrong?

look at the carby, unbolt it, soak it in a bucket of petrol overnight, pull float chamber cover off and flush with cleaner and compressed air, reassemble and see how it goes

Mq probs

Sounds like pre-ignition.
Carby overhaul, revs to 700rpm, timing set. All possible
