JESUS! Mike you did WHAT with the valves? If you stop the valves from opening and closing... How in the world can you get anything in there to compress?
Compression checks are done with ALL the sparks out and the carb propped wide OPEN! Then you do them ALL progressivly at the same time..
Doing it thisaway gives you a comparative compression of ALL the cylinders to the temp of the engine at that time..
Do it my way and get back here with ALL the readings.
