Hi,I got a Rotary-engine compression tester and the User Manual tell me
Remove both leading (lower)spark plugs and Screw the spark plug hole adapter into the leading plug hole in one og the rotor housings.
my question is:
1)If i just screw the adapter in one of the rotor housing the other spark plug take off already .is it fine?and what is the easy way to take off the spark plugs and screw the adapter in?Because i saw some thread if replace the spark plugs need to take off the Remove the end of the throttle body.any easy way ?

 

Easy way would be to take your car to a Mazda dealer and have them test the compression with your engine warm...

 

Thanks ur reply but i am living in korea no one know rx7 .i already got a compression tester just want to know what is the easy way take off the spark plug

 

Get under the car to remove the spark plugs. Its much easier to remove them from the bottom because you have more space to move your hands around and you can see the spark plugs clearly.

I've never used a Rotary engine compression tester but maybe these can help:
