As you break in an engine, the compression goes up from the rings
seating and forming a better seal.  Also, the more an engine gets
carbon deposits, the compression will go up.  There are two types
of compression test.  The dry test, which is where you just hook 
up the guage and measure, and the wet test, where you put a teaspoon
of oil in each cylinder just before the test.  If the compression is
low on the dry test but is up on the wet test, then you have a ring
problem.  If it stays down, it is either a valve or something
the oil is not reaching to.  

I heard a trick the other day on PBS Tv for getting rid of excess
carbon in the cylinders without taking the head off.  Get a windex
bottle full of water and squirt it in the carb of a hot engine while
at fast idle.  Supposedly it will flake off the carbon.  It usually
will muck up the spark plugs, so they should be replaced/cleaned
after doing this trick.
