I rotated the engine maybe three times(compression strokes) at the most only on a couple of cylinders because it did not seem like the gauge was moving up anymore. I get off at 3:00 today I will go home and do it again. How should I do it. I have a twenty dollar gauge that holds air when I put it on the air compressor so I know it works, correctly or not is another story. It is a compression test gauge with all the fittings.
