Lacking a compression tester, you can do a quick & dirty check that will just verify that you haven't barfed up any apex or side seals. If you just crank the engine with the trailing plug removed (do whatever you need to to prevent the engine from starting before you do it, and do this test on each rotor separately), you should hear a steady rythm of loud "pops" coming from the open plug hole as you crank it over, i.e., should sound like POP-POP-POP-POP-POP.... without any noticable differences in tempo/timing between the pops.
If you hear something like Pop-(silent gap)-Pop-Pop-(silent gap), or some variation instead, you're looking at a rebuild job.
All this check tells you is that your apex & side seals are functional; it doesn't necessarily tell you if the compression is sufficient for combustion.
