Hi Y'all,

I finally got to determining the compression for the AAN engine 
(RS2ed, etc).  I'm a little concerned.

Cyl #	PSI	
   1	165	
   2	150	
   3	130	
   4	150	
   5	130	

These numbers go with the engine which was producing the noises I 
reported hearing a couple of weeks ago - mild exhaust backfire on snap let-off.

What do these numbers suggest?  IOW, am I staring an engine rebuild 
in the face?

Bob
