Cylinders GOT to get plenty air during the STARTER CRANKING phase in order to get a decent cylinder pressure reading.

Watch out for that coil wire shorting out or starting a fire near that leaking carb fuel.

Cylinder pressure is a tricky thing which can be affected by the cam shaft profile. The "suggested" numbers are only a "guide line". What your REALLY looking for is all cylinders within 10% of each other.
