Update that is about as bad as it can get....

Was still in break in mileage on the engine and I have apparently lost all compression on the front rotor. I was driving as you should during break in and at 30 mph and maybe 3500 rpm the engine went to crap. All the sudden was barely idling, running so rough that the entire car was shaking.

I wasn't driving the car much at all while I figured out electrical problems and why my engine was idling very rich (10.7 afr at idle). When I pulled the leading plug for compression test the front one (same one with zero compression) was covered in gas and sandy grit. I thought I had found the cause of my poor running engine and probably my low afr...that my front leading coil wasn't igniting or was igniting weakly.

Did the compression test and the needle doesn't even budge. I pulled the tester to feel the puff of air while cranking and they are virtually non-existent. My hopes are that it's stuck seals and springs from running rich...but I realize that's a long shot.

This may spell the end of my rotary days. At the very least it will be some time before I re-rebuild it. I'm trying to finish up a 2nd degree and absolutely do not have money to spare right now.

I don't expect to get compression back on the rotor, but I'll try seafoam steaming. If I can't get it back to good compression I will at least teardown the engine and see what and why. If I find internal damage then I"m most likely done. It's getting harder and harder to find quality parts.

Sad day, sad day indeed!!
