Thanks Garry for the charts and comments and you too Tubs for your information……..much appreciated.

I am down country at present and had hoped to give the motor it’s first lake run since I bought it in 1974! Unfortunately the weather isn’t being being cooperative, with a lot of wind!
I have had it on loan to a museum for the last 25 years and feel that it is long overdue for a good run!

At Richard’s suggestion I tried yesterday to buy two Champion R11 plugs locally, but no luck, so
I will wait until I am back in Auckland and see how I get on there and with the other plug suggestions.

Interesting to note that NGK seems to be the most common plug brand here in NZ. However, I don’t know if there is an equivalent in in their range.

Thanks very much once again. It will be interesting to see how I get on.
