First thing I'd do is pull the valve cover and make sure everything is in tact. Check valve lash. If that all checks out a tear down is in order.

These will not have compression while cranking the engine over if the throttle plate is closed.

Rework was to remove idle speed screw due to fouling b4 plugs ( not needed ).

No air can get into the combustion chamber and because of that make sure you open the throttle a bit while cranking to test compression.
