how is my compression? ,mazda said it's right where it should be but it seems low compared to other board members.....
rotor1.. 6.6,6.2,6.7 @229rpm rotor2 6.1, 6.0, 6.4@226rpm
the car is a 93 with 39k on it

 

I wouldn't worry too much about it. If the car starts and runs OK, I would just leave it alone and enjoy it!

i have similar compression as you, but i do have 97k on the motor. just like wargasm said, if it starts and idles dont worry too much.

 

From what knowledge I have gained on here, its more important to have the numbers for each rotor close than it is to have higher numbers.

 

That is pretty good for such a low cranking rpm. The differential (0.7kg/cm^2) is a bit higher than ideal but overall you are totally fine.

 

yeah... its all about them being equal... you should be alright but wary
