Update: Got the GT running again. It seems the CDI went bad. I put a new CDI on and it immediately got the spark back. I'm not sure if the compression test could have shorted out the CDI, I don't know how it could have. I think my problems were just a coincidence that they happened right after I did the compression tests. The Peugeot CDI didn't short out after the test, that was a carb problem.

If you turn the engine fast enough with the CDI conected and sparkplug not grounded that can damage the CDI. Probably that's what happened.
