1. Normal
The n o rmal insulator tip is gray, tan or light brown. Th ere will be few
combustion deposits. The electrodes are not burned or eroded. This
indicates the proper t y p e and heat range for the engine and th e service.
NOTE: The tip should not be white. A white insulator tip indicates
overheating, caused by use of an improper spark plug or
incorrect carburetion adjustments.
