Message	or 40% "low". If you do any research on leakdown, or cylinder leakage tests (same thing, different name), it says 10% is about the low end of a high performance motor, and 15%+ is about the low end for any motor. How can losing 70% of your air/fuel charge be "moderate"; it's nuts. Mike ------------------------------------------------------
