Can you post your compression numbers? Blinking cell means misfire...

FYI to perform a compression test on a rotary engine you need a specific compression tester. The one used for piston engines will not work. Were the ignition components changed under your ownership or this is what the previous owner told you?

I believe it was a pistoon compressor tester which is same compressor I had used for my fc before

I ask him n front rotor was 88 rear rotor was 60. And. All sidenof the rotor was banging evenly but very low

The compression numbers I have seen include one for each face of the rotor. This means that you need to have 6 numbers (3 for each rotor). I feel that your friend does not know much. Maybe you need to consider taking it to a dealer or a rotary specific shop for a valid compression.

The numbers I put would be compression of each rotor

The numbers ur talkin bout would be use to tell which face of the rotor is damage

Over all each rotor should hold a certain compression which I believe should be higher then 90psi

I am afraid you will include me to your list of idiots telling you that you have compression issues. If your ignition is good, and you have no cat related issues the symptoms you have listed lead to a bad engine. Maybe someone else in here has a better idea/suggestions for your problems.
