I have an 85 Mazda RX7.
Came out one day and it would not start.
So I made sure it was getting fuel.
Then made sure I had good spark to all the plugs.
So decided to do a compression test. On the 2 spark plugs closes to the radiator I have 60psi but on the back 2 closes to the fire wall there is 0 compression.
I have worked on lots of cars but never a rotary motor, but seems to me there should be the same compression at all spark plug holes.
Any help or advice would be appreciated.
Thanks.
