This tool is used for accurately measuring squish clearance. Compatible with all Zenoah / CY / RCMK RC style engines and the GP460. Also compatible with other engines that use a "vertical" 10mm spark plug. To get the most power from your engine the squish clearance should be set as close as possible without the piston hitting the top of the cylinder during operation. Use this tool to set the squish right where you want it for maximum compression and power. Instructions included, and can be downloaded HERE
