While doing the test, the throttle and choke plates must be fully open for an accurate test. Fully depress the accelerator while cranking the engine. Screw the tester into a spark plug hole and turn the engine 4 compression strokes. You will be able to hear the cranking speed slow as the tested cylinder comes up on its compression stroke.

Spark knock problems may be encountered with high compression engines. If engine parts were “mixed and matched” from different suppliers, the actual compression ratio may differ substantially from the expected value. You cannot estimate compression ratio with cranking compression tests, as camshaft timing usually causes an erroneous low ...
