"I used a craftsman compression tester. I checked with the engine at normal operating temperature. I removed all 4 plugs (they all looked normal). I cranked the engine with the throttle wide open, and cranked about 12 times per cylinder. Each cylinder behaved the same building up pressure in about 4 compression strokes."
.................should be done on a cold engine. Warm will cause the pressure to read higher. Aluminum expands when hot thus creating a higher compression range/reading.
