    Kyle, the correct piston orientation is when the lower sloped side of the piston faces the exhaust cover. If you were unaware of that during assembly, then odds are you have one or more pistons installed backwards.

    Regarding the compression test method, I am not sure if your cordless drill is generating enough RPM for an accurate reading. When I rope over a motor, there are approximately 5-6 piston strokes that occur in a fraction of a second. Try roping one over and see if that changes anything.
