Compression Check
#12
Actually, Mazda uses the trailing position versus the leading.
Also, Mazda numbers apply to engines that are warmed up, not cold.
Although not explicitly mentioned, you need to prop the throttle open.
I just wrote up a page for this...

I wouldnt do the "quick way" for this find your self a dealer or a rotary shop that has a Mazda Compression checker.
We did mine and it looked good but the car still ran like crap. Went to the dealer had them do it with the factory tool and then we knew why it ran like crap.
