I have reopened this thread for the sake of completeness. Over time the cutting out became more frequent. I narrowed it down to being associated with stopping after rapid deceleration, rather than right hand turning.
It seemed to me that the weakening of the fuel mixture that could occur as a result of air leaking in around the worn throttle spindle might be the cause. This would be particularly significant on rapid deceleration with the car pushing the engine along at high revs causing greater vacuum downstream of the closed throttle spindle.
A carburettor repair specialist confirmed my suspicions about this and fitted teflon throttle spindle bushes and a new spindle. This has cured the engine cutting out. It has also eliminated the occasional backfiring running downhill with throttle closed.
No more embarrassment with engine cut outs.
Cheers
