No compreesion on front rotor.....

I'm new to the rotary engines, here's my problem........ I was driving to work one day when I went to pass a car on the freeway. I got around the car, moved over, went to give it gas and it acted like it was misfiring!!!! Engine never got hot, oil pressure was good, no warning at all!!!! (drove it back from Oakland to Sacramento with no problems at all, other than the obvious lack of power going uphill!!!!)..... Not sure what the problem is....... Any suggestions sure would be helpful, need to decide whether to rebuild it or what?????

Did you actually compression test the engine?

I did a compression test according to the Haynes manual........ gauge needle hardly moved when testing the front rotor, needle bounced 3 times to about 75-80 lbs on the rear rotor.........

Do the test again to verify the poor compression on rotor #1. Make sure that the tester is sealing at the spark plug hole and that whoever cranks the engine holds the gas pedal to the floor. If you still get low readings it's probably time for an engine rebuild or replacement.

Yes it will work, but it will be half a car. Its also not good to run on 1 rotor so a rebuild/replacement is the way to go.

You can run on one rotor, ive done it for a week while waiting for a replacement engine to arrive. Fuel economy gets greatly reduced (more than 50%), you have 0 torque for climbing hills without dropping to second gear, and the sound and smell is most aggrivating.

Plan on rebuilding the engine or find a lower mileage used engine that will tide you over till the inevitable.
