?I would check gauge accuracy and make sure you are taking compressions at engine operating temperature, with a good starter and battery giving you at least 200-400 RPM and the throttle plate is held wide open and choke plate must be open. If still too low then pergorm a compression leak down test to pin point the leaks.
