yeah you can't rely on the pressure building in the cylinders on the compression stroke for a leakdown test. you have to pressurize it with an air compressor. A lot of times the compression tester gauges have a quick connect fitting that will work with your air hose... you can just use the hose and hook it up to air. i thought that's what you were doing.
