Thanks for all the advice and comments. I always thought a spark plug was just a spark plug so I have learned a great deal from your replies. Anyway I managed to buy a set of NGK AB-6 plugs which appear to be Japanese in origin. Having installed them and checked and cleaned battery terminals the old girl started on the crank handle without the choke.
