Works on gasoline engines including domestic, import, motorcycle, marine, snowmobile, ATV's, and small engines.Ĭompression testing is accomplished by connecting the compression tester to the spark plug hole. Bad compression readings can mean worn piston/rings or cylinder walls, worn or sticking valves, and bad head gaskets or cylinder heads, all of which can cause driveability issues.ĭigital gauge powered by 9V battery, not included. ![]() A convenient push-button side release valve relieves pressure for repeat testing.
