[Diy_efi] Spark Plug readings

[Bob Wooten]

what is high speed glazing?  does that mean that it "glazed" quickly or that
running the engine @ a high rpm caused "glazing"?

What is glazing?  are you talking about the very shiny chocolate sauce on
the one plug?

Worst case of high speed glazing I seen in years.
Variety of problems to generate these.
Too hot of plug too much timing, and/or poor distribution.
2nd plug has seen some serious detonation.
