      With the CHT washer probe that goes under the spark plug I cut off the washer on the spark plug.

      Wanted to see if others did the same?

        I do. Granted it’s a LO206 engine. We do it so the spark plug is seated as designed. I feel two washers wouldn’t put the spark where it needs to be for proper combustion.

          Hey Wade,

          on a ZR3  JR RACE CAR Engine, you are good to run with or with out spark plug washer while running the CHT sensor

          In almost all Jr Dragster Engines if you run the CHT sensor you can cut off the washer for the spark plug.
