    The stock cranking compression of a 951 @ sea-level is 150 psi.

    so is 130 on both cylinders bad and how will that affect performance?

    make sure you are checking compression with the throttle wide open and your battery is strong

    How good is your compression gauge, It takes a good one to read accurate. More importantly is that your cylinders are within 10% of each other.
