[SEL] A spark plug question from a new member

[Paul Pavlinovich]

Google failed you because you searched for Buzacott - if you searched 
for Rosebery you would have found my pages :)

The Buzacott is a Rosebery in disguise.

The plug you want is Champion 25 18mm tapered "copper plus" marine 
engine plug - they fit reasonably well. The thread isn't exact but it 
works. You can still get the right plug from a specialist supplier (at 
an engine show generally - go find Rally Badges or someone like that).

Regards
Paul
