Yeah on my compression tester i took the adaptor off it (spark plug thread on one end) and adapted it to an air compressor.
This trick does work, but there are times when you have a hard time building enough pressure to hold the valve up with enuf force to press the springs down. You have to add oil down the plug whole sometimes and rotate the valves around to get that sealing happening again. Very frustrating i tell you. But not impossible.
