Thanks to all - I am running mogas so there is no lead problem like
when I ran avgas. This problem presents itself every 3 or 4 years, I
guess that is why I didn't have anything to go in the electrode gap.
I think I may try a pick for the main cavity and a feeler guage to
clean the electrode gap and if that doesn't work I'll go the carbide
route. Incidentally the identical looking carbide blaster turned up
on Harbor Freight for $10. Nothing is sacred anymore.

And then I would buy some glass bead to replace the carbide
grit. Cleans just as well and is easy on the plugs. Make sure you get
ALL grit out of the plug, whether it's glass or carbide, or it'll fall
into the cylinder when you reinstall the plugs and extensive cylinder
scoring will result.
