I got an oddball reading on my Eldo last night- I had not compression tested it before, as it runs very well and I have had no problems with it. But looking at Greg's recent posts and the fact that I was procrastinating in the garage led me to pull out my trusty compression gauge- and on my warmed up engine with both plugs pulled and throttle WFO- I get a reading of 205lbs PSI - both sides identical. I have used this exact gauge on at least 4 or 5 other loop engines over the years and different stages of their lives, and all have registered between 130lbs and 165lbs-. I have had this engine apart and there is very very little carbon build up. What else could be causing the high reading? I should mention that when I torque my head bolts I generally overtorque them about 4 ft lbs from fafotry spec (to 42 ft lbs I believe) , but I have done this on the other motors that have been compression tested as well.
