Briggs & Stratton gave me such a wide variance on it that I
didn't bother to write it down, telling me it depended upon
the temperature and so many other factors that the number
wasn't all that important.


briggs doesn't publish compression specs because they have a
compression release and the number mean squat.
the valve face and seat wear, causing you to lose clearance. check
the clearance set them at .006 and .010.


as for the guy with the quadrajet, did the tech forget about the
famous secondary metering well leak???
