      Hi All

      Could someone please give me an idea of compression  requirements and any other suggestions to get the above motors running.

      Currently the best is  35lbs on both cylinders on both  motors.

      Thanks in advance

          As Al says, 60 minimum, but 70 to 75 to be a great idler.

          Prepare to be boarded!
