Mica Spark Plugs and Engine Compression by raheyo6168 is a document available to read on EtoBox.
This document details a test conducted to determine the highest engine compression pressure that can be used with representative mica spark plugs in a Liberty single-cylinder engine without preignition occurring. The test found that Brewster-Goldsmith and K. L. G. mica spark plugs could be run without preignition up to 86 and 106 pounds per square inch of compression pressure, respectively. Preignition is usually not encountered in flight service due to lower compression pressures from partial throttle or h
