>>>*I have been watching this thread for awhile, time to mention a couple of things.

First, accuracy is important in testing the cylinder pressure, other wise it is just a balance test. In the old days with the equipment we had then and the manufacturing tolerances at the time, we considered 20% variation to be normal.

In today's world it should be within 10% and I have tested many 22RE engines that cranked within one pound of each other.

Your heading tells the likely story. Sluggish with poor mileage. Your compression numbers are low enough to affect that some but not cause it.

So more likly a rich condition. Rich will demonstrate as sluggish, poor upper RPM response, poor mileage. Lean typically will spit, hesitate, or just won't go.

An exhaust analysis will offer an indication, if the reading is high then she is likely rich.

Another possible is the ignition timing isn't advancing properly, put a timing light on her and bring the engine up to 3000 RPM and see what it reads.

Still another one that is rarer but possible is the dampner timing mark slipping. This would mean an inaccurate setting.

The basic causes of poor top end are inaccurate timing or too much fuel...Of course if the valve seal or rings seal are poor, no amount of tuning will cure that....*EB
