Hi all,

i have looked at the service/shop manual and could not figure out what the compression numbers are suppose to be on our type S motors.

some say it should be around 230-235psi while i see others are getting between 180-195psi.

if anyone with the knowledge or can direct me to the right direction i would greatly appreciated.

thanks for the help

It's not so much how high the readings are, but how close they are.
You want to see the cylinders within a few pounds of each other.

Anything from 180 on up should be ok.
