Paul-

You asked for compressions on the PPort.  Bearing in mind I have low
compression rotors in my engine, I measured 50psi on each rotor.  This
measurement was taken cold -- the engine was not pre-run or otherwise
warmed up.

Sounds like an average.
How was that done Mark? Did you take the schrader valve out
of the compression tester gage and watch it pulse as you turned
the engine over with the starter?
