you run a compression test mainly to determine the condition of the piston rings and cylinder walls. low compression could mean to rebuild. high compression is good and will usually mean the engine is still in sound shape.
You can also lose compression through your heads. You can compression test with a simple compression tester from any auto parts store. Remove one plug at a time, thread the tester into the cylinder, remove your coil wire, and crank the motor for a few seconds.
