Spark electrode MUST be engulfed in flame when it lights off

Spark electrode ceramic insulator can not be cracked....ground tracking

Spark electrode gap 1/8"

The electrode did look good, gave it a quick cleaning with some fine emery cloth porcelain was still shinny with no cracks in it. guess looks can be deceiving. As soon as I installed the new one and made a few adjustments it fired right up.
