Poor man's compression test:
Hold finger over spark plug hole while cranking, feel pressure pulses.
Poor man's comprssion test 2:
If turning by hand, does the engine (with plugs in) sound like Lub..psht..Lub..psht..Lub (good rotor) or like lub.....lub.....lub (bad rotor.)
Please note that a real compression test is always superior and can be done for free. Buy the compression tester (ordinary piston engine tester will do.) Hold the release down and crank, observe all three spikes. Then return tester.
