John,

The actual numbers are not as important as how well they match between
cylinders.  If all 4 are between 180-190 (meaning within 3% of the average),
then that is very good.

Meant to mention before, my TRactor motors have always had a pretty strong
'pulse' if you hold your hand above the open oil filler with the engine
running.  I'm not sure why that is, but it doesn't seem to necessarily
indicate a problem.
