What is a reasonable compression range ?



Exp:  If I leave the other spark plugs in place, but wedge the throttle

open

and measure the pressure with a gauge threaded in the spark plug hole,

what is low (130 PSI), normal range (150-170) or high (180+) ?



I can only guess my engine is stock.



Presuming I don't squirt a little oil in to "seal" the rings...
