Yes I was wrong, despite having seen them in that Champion catalogue filed away.
Tempest do not sell one I should have said. As I was using them as reference material. My humblest apologies. Something about the president from Tempest telling me "do not gap them and we don't sell a tool to do it anyway" might be why
And they do not encourage it because of damage to the tips.
Bottom line is they should not need gapping.
Will pay more attention to detail in future. Sorry!
