    150/155 psi is about right for the 720 motor

    Around the 150 mark is good. Lower readings dont necessarily mean anything bad. What you do want is that both cylinders readings are close to each other. A 10% difference is not uncommon, but dont recommend allowing larger differences unless you thoroughly check condition of cylinders/pistons.
