ABSTRACT:
A simple and compact tool for use with aircraft spark plugs to reset the spark gap, which enables a person to hold the spark plug to the tool, hold a gauge to the spark plug, and squeeze the electrodes of the spark plug to set the gap, all under field conditions. The tool includes a pair of bars pivotally connected at one end and a nut fixed to a first of the bars to loosely hold a spark plug, the nut having a cut-away portion to permit the second bar to move over a spark plug held by the nut, and the second bar having a recessed edge which can move against an electrode of the spark plug to bend it.
