Disable the ignition module or coil.
Insert the compression tester into one cylinder spark plug hole at a time.
Hold the throttle to full open position to ensure the engine gets adequate air intake.
Crank the engine continually for at least five to 10 full revolutions to obtain an accurate reading on the compression tester.



So thats it
Pretty much but I have NEVER held WOT!!

Could be anywhere from 120 - 150 depending on the wear of the engine. Looking mainly for all cylinders to be w/i 10-15% of each other.
